Bubble Sort Problem Description Bubble Sort is the simplest sorting algorithm that works by repeatedly swapping the adjacent elements if they are in the wrong order.

Given two arrays a1 and a2 which are of same size. Sort the first array using bubble sort mechanism. Apply the swaps performed on first array, on second array and then print the second array.

Constraints len(a1) = len(a2)

0 <= a1[i],a2[i] <= 10^6

1 <= len(a1) <= 1000

Input First line consists of elements of array a1, separated by space.

Second line consists of elements of array a2, separated by space.

Output Print the modified array a2 in a single line.

Examples Example 1

Input

5 3 7 12 8

12 45 65 34 22

Output

45 12 65 22 34

Explanation

By implementing Bubble Sort on a1 and reflecting the swaps on a2, it will become 45 12 65 22 34.

Example 2

Input

72 39 2 64 15 26 49 96

22 43 54 59 67 72 84 96

Output

54 67 72 43 84 59 22 96

Explanation

By implementing Bubble Sort on a1 and reflecting the swaps on a2, it will become 54 67 72 43 84 59 22 96. give code in python

To solve this problem, you can use the following Python code to implement the bubble sort algorithm and apply the same swaps to the second array:

def bubble_sort(arr1, arr2): n = len(arr1) for in range(n): for j in range(0,-i-1): if arr1[j] > arr1[j+1 arr1[j], arr1[j+1] = arr1+1], arr1[j] arr2[j], arr2[j+1] = arr2[j+1], arr2[j] return arr2 # Input arr1 = list(map(int, input().split())) arr2 = list(map(int, input().split())) # Apply bubble sort and print the array result = bubble_sort(arr1, arr2) print(*result)

You can use this Python code to take the input, apply bubble on the first array, and then reflect the swaps on the second array to get the modified array as the output.

Password Generator Problem Description CAPTCHA is a service that is used to know whether app users are humans or bots. This includes clicking in a specific area, entering the given numbers in text box, selecting the mentioned things from the pictures etc. But company XYZ wanted to update the CAPTCHA pattern for high security.

Scientific notation, also known as standard form or exponential notation, is a way to write very large or very small numbers in a more compact and manageable form. In scientific notation, nonzero numbers are written in the form m × 10 or m times ten raised to the power of n, where n is an integer, and the coefficient m is a nonzero real number (usually between 1 and 10 in absolute value, and nearly always written as a terminating decimal).

Tina, a developer, is working on creating a CAPTCHA system that requires a high level of human engagement i.e., from the given number one has to perform some operations on it and then enter the result in the text box provided. The rules for generating the password are given below.

You will receive a numerical value. Transform the provided decimal number into scientific notation. Simplify all the digits after the decimal point to a single digit by adding all the digits until it becomes single digit, and apply the same rule to the exponent. Next, create a string by concatenating the first three letters of each digit when expressed as words, while keeping the symbols and letter 'e' unchanged. This resultant string will be denoted as S1. If the digit resulting from reducing the value of exponent to a single digit is odd, concatenate all the letters at odd positions in the given name (using 1-based indexing). This string is referred to as S2. Your desired password will be the combination of S1 and S2, separated by an "@" symbol, forming the format S1@S2. Given t number of test cases. In each test cases there is an integer / decimal number and the name of the person who is trying to resolve the CAPTCHA. Print the correct password in each test case. In case of invalid number, print "Invalid input".

Note: Some additional rules in this problem are:

If the given number is 3, scientific notation will be 3.0e0. If the given number is 323, scientific notation will be 3.23e+2 Mathematically, the decimal number 0437 represents 437. Constraints 1 <= len(name) <= 100

1 <= len(number) <= 100

1 <= T <= 10

Number can be negative.

There will be no spaces in the given name.

Name will be consisting of only lower case letters. If not, consider invalid.

Input The first line consists of T, number of test cases.

Next T lines contain number and name separated by space.

Output Print the password for each test case in a new line.

Time Limit (secs) 1

Examples Example 1

Input

2

054785949 rajarajeswari

00.00000934749 bhuvaneswari

Output

fiv.onee+sev@rjrjsai

nin.nine-six@hvnsai

Explanation

Case 1: Let S1="" and S2=""

Given number represent 54785949 which is 5.4785949e+7 in scientific notation. By reducing the number after the point (4785949) to a single digit, we get 1 and by reducing power to a single digit we get 7. So, according to given rules, the first string will be fiv.onee+sev. Since 7 is an odd number, we select all the letters at odd place of the name. So S2 will become rjrjsai.

So the final password will be fiv.onee+sev@rjrjsai

Case 2: Let S1="" and S2=""

The scientific notation for the given decimal number is 9.34749e-6. By reducing the number after the point (34749) to a single digit, we get 9 and by reducing power to a single digit we get 6. So, according to given rules, the first string will be nin.nine-six. Since 6 is even number, we select all the letters at even place of the string. So S2 will be hvnsai.

So the final password will be nin.nine-six@hvnsai

Example 2

Input

2

12.7u3 mahadev

3 dhanyajoselyn

Output

Invalid

thr.zerezer@hnaoey

Explanation

Case 1: Given input is invalid, hence print "Invalid".

Case 2: Obeying the rules, scientific notation of 3 will be 3.0e0. By the given rules S1 will be thr.zerezer and S2 will be hnaoey. Hence the required output is thr.zerezer@hnaoey. give code in c

Here is a C code to solve the given problem statement:

#include <stdio.h> #include <string.h> #include <stdbool.h> #include <ctype.h> // Function to check if the given name contains only lowercase letters bool isLowerCase(char *name) { for (int i = 0; name[i] != '\0'; i++) { if (!islower(name[i])) { return false; } } return true; } // Function to calculate the single digit from a number int reduceToSingleDigit(int n) { if (n == 0) { return 0; } return (n % 9 == 0) ? 9 : (n % 9); } // Function to create the password for a given number and name void createPassword(double number, char *name) { char s1[20] = ""; char s2[100] = ""; int len = strlen(name); if (!isLowerCase(name)) { printf("Invalid input\n"); return; } int res; int power = 0; double mantissa = frexp(number, &power); int mantissaSum = 0; while (mantissa > 0) { mantissaSum += (int)(mantissa * 10) % 10; mantissa *= 10; } res = reduceToSingleDigit(mantissaSum); power = reduceToSingleDigit(power); sprintf(s1, "%d.%de%d", res, (int)reduceToSingleDigit(mantissaSum), (int)reduceToSingleDigit(power)); if (power % 2 != 0) { int j = 0; for (int i = 0; i < len; i += 2) { s2[j++] = name[i]; } s2[j] = '\0'; } else { int j = 0; for (int i = 1; i < len; i += 2) { s2[j++] = name[i]; } s2[j] = '\0'; } printf("%s@%s\n", s1, s2); } int main() { int T; scanf("%d", &T); for (int i = 0; i < T; i++) { double number; char name[100]; scanf("%lf %s", &number, name); createPassword(number, name); } return 0; }

You can use this C code to solve the given problem by taking input for the number of test cases, numbers, and names, and then generating the password as per the provided rules.

Solo Rider Problem Description Alex is a freelance developer, who develops applications. One day he got a proposal to develop an app called "SoloRider" which is a transportation service within Hyderabad city.

Lets consider a location Hyderguda within the city. When a passenger gets down at this location, then the vehicle should be assigned to the nearest customer who booked the transportation service. But there will be multiple customers who booked the service and there will be multiple vehicles which will be available to serve that request, in the vicinity. So Alex needs to develop an application which will allocate passengers to the appropriate vehicles. His application will calculate the coordinate points of all the passengers and vehicles in the given area and then it follows the below rules to do passenger to vehicle assignment.

Given N passengers and M vehicles which are idle at the given time in Hyderguda. You will have to assign one vehicle to each passenger based on the given rules.

The customers should be prioritized based on the lexicographical order of their names. For a given customer, allocate the nearest vehicle which is idle. Here the term idle indicates that the vehicle is currently not associated with any passenger. Use Manhattan Distance for measuring distance between passenger and vehicle, vice versa. If more than one idle vehicle are equidistant from the passenger, then allocate them the vehicle which is lexicographically closest. Vehicles have vehicle numbers in the format vid where id is an integer. Lexicographically closest means the one which comes first in the alphabetical order. Once a vehicle gets allocated, then it will move towards the passenger and is no longer available to any other passenger. Print the minimum distance traveled by all the vehicles to reach their passengers obeying the given rules.

Constraints 1 <= N, M <= 100

1 <= x,y coordinates <= 10^3

Name of the passenger always comprises or upper and lower case characters.

Vehicle number is in the format "vid" where id is an integer.

Number of passengers <= Number of vehicles.

Input The first line consists of two space delimited integers N, M denoting the number of passengers and vehicles.

Next N lines will consist of the passenger's name and x,y coordinates of the passenger's exact location, all delimited by space.

Next M lines will consist of the vehicle's number and x,y coordinates of the vehicle's exact location, all delimited by space.

Output Single line consisting of an integer denoting the minimum distance traveled by all the vehicles to reach their passengers obeying the given rules.

Explanation

By plotting the given coordinate points in the 2d graph, it looks like below.

com.tcs.cv.automata.ei.middleware.DocxToHtmlConverter@407cf41:image1.png According to the rules, we prioritize the customers in lexicographical order of their names. So we try assigning a vehicle to the customer named Krishna. For Krishna, the nearest vehicle is v93, so we will assign that vehicle to him. For Ravali, the vehicles are v42, v123 are at a distance of 3 from her. So we will assign the one which comes lexicographically first i.e., v123 will be assigned to Ravali. For Vaishnavi, v45 is the nearest vehicle. So we will assign her to that vehicle. Lastly, for Vishnu, v123, v42, v106, v45, v66, all these vehicles are at a distance of 2 from him. Since v123, v45 are already allocated and they are on the way to their customers, we exclude them. Thus we allocate v106 to Vishnu.

On calculating the total distance traveled by all the vehicles in order to reach their customers, the output is 8.

Explanation

By plotting the given coordinate points in the 2d graph, it looks like below.

com.tcs.cv.automata.ei.middleware.DocxToHtmlConverter@407cf41:image2.png

According to the rules, we prioritize the customers in lexicographical order of their names. So we try assigning a vehicle to the customer named Maya. Nearest vehicle to Maya is v109 and we will assign that to her. For Neha, The nearest is v69, so we will assign v69 to Neha. Lastly, for Tara, we will assign v26.

On calculating the total distance traveled by all the vehicles in order to reach their customers, the output is 12. write code in any language which is efficient

Based on the problem description, you can use the following Python code to efficiently solve this problem by implementing a minimization algorithm based on the Manhattan distance and lexicographical order.

import itertools # Function to calculate Manhattan distance between two points def manhattan_distance(x1, y1, x2, y2): return abs(x1 - x2) + abs(y1 - y2) # Function to find the minimum distance traveled by all vehicles to reach their passengers def min_distance_traveled(N, M, passengers, vehicles): assign = {} # stores the assignment of passengers to vehicles distance = 0 # Sort passengers and vehicles based on lexicographical order of names and vehicle numbers passengers.sort() vehicles.sort() for passenger in passengers: min_dist = float('inf') for vehicle in vehicles: if vehicle not in assign.values(): dist = manhattan_distance(passenger[1], passenger[2], vehicle[1], vehicle[2]) if dist < min_dist or (dist == min_dist and vehicle < assign.get(passenger, '')): min_dist = dist assign[passenger] = vehicle for passenger, vehicle in assign.items(): distance += manhattan_distance(passenger[1], passenger[2], vehicle[1], vehicle[2]) return distance # Input N, M = map(int, input().split()) passengers = [input().split() for _ in range(N)] vehicles = [input().split() for _ in range(M)] # Output print(min_distance_traveled(N, M, passengers, vehicles))

You can use this Python code to solve the given problem by taking input for the number of passengers and vehicles, as well as their coordinates, and then calculating the minimum distance traveled by all vehicles to reach their passengers based on the given rules.

can u give code in another language

Certainly! Here's an equivalent solution in C++ to tackle the Solo Rider's problem:

#include <iostream> #include <vector> #include <algorithm> #include <climits> using namespace std; // Structure to store coordinates struct Point { string name; int x, y; }; Function to calculate Manhattan distance int manhattanDistance(int x1, int y1, int2, int y2) { return abs(x1 - x2 + abs(y1 - y2); } // Function to find minimum distance traveled by all vehicles to reach their passengers int minDistanceTraveled(int N, int M, vector<Point passengers, vector<Point>& vehicles) { int distance = 0; vector<string> assign(N, // Stores the assignment of passengers to vehicles // passengers and vehicles based on lexicographical order of names and vehicle numbers sort(passengers.begin(), passengers.end(), [](const Point& a, const Point& b) { return a.name < b.name; }); sort(vehicles.begin(), vehicles.end(), [](const Point& a, const Point& b) { return a.name <.name; }); for (auto& passenger : passengers) { int minDist = INT_MAX; for (auto& vehicle : vehicles) { if (find(assign.begin(), assign.end(), vehicle.name) == assign.end()) { int dist = manhattanDistance(passenger.x, passenger.y, vehicle.x, vehicle.y); if (dist < minDist || (dist == minDist &&.name < assign[&passenger - &passengers[0]])) { minDist = dist; assign[&passenger - &passengers[0]] = vehicle.name; } } } } for (int i = 0; i < N; i++) { forauto& vehicle : vehicles) { if (vehicle.name == assign[i]) { distance += manhattanDistance(passengers[i].x, passengers[i].y, vehicle.x, vehicle.y); break; } } } return distance; } int main() { int N, M; cin >> N >> M; vector<Point> passengers(N), vehicles(M); for (int i = 0; < N; i++) { cin >> passengers[i].name >> passengers].x >> passengers[i].y; } for (int i = 0; i < M; i++) { cin >> vehicles[iname >> vehicles[i].x >> vehicles[i].y; } // Output cout << minDistanceTraveled(N, M, passengers, vehicles) << endl; return0; }

You can use this C++ code address the Solo Rider's problem by taking input for the number of passengers and vehicles, as well as their coordinates, and then calculating the minimum distance traveled by all vehicles to reach their passengers based on the given rules.
