HackerRank Counting Sort 1 problem solution

In this HackerRank Counting Sort 1 problem, you have given a list of integers, count and return the number of times each value appears as an array of integers.

Problem solution in Python programming.

```n = int(input())
ar = list(map(int, input().split()))

tot = [0]*100

for j in range(0,n):
temp = ar[j]
tot[temp] += 1
print(*tot, sep =' ')    ```

Problem solution in Java Programming.

```import java.io.*;
import java.util.*;

public class Solution {

public static void main(String[] args) {
Scanner in = new Scanner( System.in );
in.nextLine();  // not used
System.out.println( outputString( count( convertToInts( in.nextLine().split( " " ) ) ) ) );
}

public static int[] count( int[] ar ) {
int[] count = new int[100];
for( int nbr : ar ) {
count[nbr] += 1;
}
return count;
}

private static String outputString( int[] ar ) {
StringJoiner joiner = new StringJoiner( " " );
for( Integer value : ar ) {
}
return joiner.toString();
}

private static int[] convertToInts( String[] values ) {
int[] parsed = new int[values.length];
for( int i = 0; i < values.length; i++ ) {
parsed[i] = Integer.valueOf( values[i] );
}
return parsed;
}
}```

Problem solution in C++ programming.

```#include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
using namespace std;

int main() {
int n, val;
int A[100];
for (int i = 0; i < 100; i++) {
A[i] = 0;
}
scanf("%d", &n);
for (int i = 0; i < n; i++) {
scanf("%d", &val);
A[val]++;
}
printf("%d", A[0]);
for (int i = 1; i < 100; i++) {printf(" %d", A[i]);}
printf("\n");
return 0;
}```

Problem solution in C programming.

```#include <stdio.h>
#include <string.h>
#include <math.h>
#include <stdlib.h>

int main()
{
int i,j,n,a[1000001];
int c[100]={0};
scanf("%d",&n);
for(i=0;i<n;i++)
{
scanf("%d",&a[i]);
c[a[i]]++;
}
for(i=0;i<100;i++)
printf("%d ",c[i]);
printf("\n");
/* Enter your code here. Read input from STDIN. Print output to STDOUT */
return 0;
}```

Problem solution in JavaScript programming.

```'use strict';

function processData(input) {
var lines = input.split('\n'),
len = parseInt(lines[0], 10);

lines = lines[1].split(" ");

var A = Array.apply(null, new Array(100)).map(Number.prototype.valueOf, 0);

for (var i=0; i<len; i++) {
A[parseInt(lines[i], 10)]++;
}

console.log(A.join(" "));
}

process.stdin.resume();
process.stdin.setEncoding("ascii");
var _input = "";
process.stdin.on("data", function (input) { _input += input; });
process.stdin.on("end", function () { processData(_input); });```
