Hackerrank The Full Couting Sort problem solution YASH PAL, 31 July 2024 In this Hackerrank The Full Counting Sort problem we have given a list of strings associated with integers. we need to sort the list and print the values in sorted order. Topics we are covering Toggle Problem solution in Python programming.Problem solution in Java Programming.Problem solution in C++ programming.Problem solution in C programming.Problem solution in JavaScript programming. Problem solution in Python programming. import collections def tc(n, arr): d = collections.defaultdict(list) for i in range(n): k,v = arr[i].split() if i < n//2: d[int(k)].append("-") else: d[int(k)].append(v) od = collections.OrderedDict(sorted(d.items())) print(" ".join([" ".join(l) for l in od.values()])) n = int(input()) arr = [] for _ in range(n): arr.append(input()) tc(n,arr) Problem solution in Java Programming. import java.io.*; import java.util.*; public class Solution { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); int entries = scanner.nextInt(); StringBuilder[] freqs = new StringBuilder[100]; for (int i = 0; i < entries; i++) { int idx = scanner.nextInt(); if (i < entries / 2) { freqs[idx] = freqs[idx] == null ? new StringBuilder("-") : freqs[idx].append(" -"); scanner.next(); } else { freqs[idx] = freqs[idx] == null ? new StringBuilder(scanner.next()) : freqs[idx].append(" ").append(scanner.next()); } } for (int i = 0; i < freqs.length; i++) { if (freqs[i] != null) { System.out.print(freqs[i].toString()); System.out.print(" "); } } System.out.println(); } } Problem solution in C++ programming. #include <cstdio> #include <iostream> #include <vector> #define MAX 1000001 using namespace std; int num; vector<int> cnt[101]; string name[MAX]; int val[MAX]; int order[MAX]; int main(){ cin >> num; int stop = num/2; int temp1; string temp2; for(int x = 0;x<num;x++){ cin >> temp1 >> temp2; val[x] = temp1; name[x] = temp2; cnt[temp1].push_back(x); } for(int x = 0;x<100;x++){ for(vector<int>::iterator it = cnt[x].begin();it!=cnt[x].end();++it){ if((*it)<stop) cout << "- "; else cout << name[*it] << " "; } } return 0; } Problem solution in C programming. #include <stdio.h> #include <string.h> #define MAXN 1000000 #define MAXNUM 100 #define MAXSTR 10 int main() { long i, j, n, num[MAXN]; static char str[MAXN/2][MAXSTR]; scanf("%ld", &n); for ( i = 0; i < n/2; i++ ) { scanf("%ld", &num[i]); scanf("%*s"); } for ( i = n/2; i < n; i++ ) { scanf("%ld", &num[i]); scanf("%s", str[i-n/2]); } for ( i = 0; i < MAXNUM; i++ ) { for ( j = 0; j < n/2; j++ ) { if ( num[j] == i ) { printf("- "); } } for ( j = n/2; j < n; j++ ) { if ( num[j] == i ) { printf("%s ", str[j-n/2]); } } } return 0; } Problem solution in JavaScript programming. function processData(input) { //Enter your code here var ar = input.split('n'); var n = parseInt(ar.shift(), 10); var sorted = {} for(var i = 0; i < n; i++) { var space = ar[i].indexOf(' '); var pos = parseInt(ar[i].substr(0, space), 10); var chars = i < n/2 ?
