Accenture Coding Problem 1

Given a string, find the frequencies of each of the characters in it.
The input string contains only lowercase letters. The output string should contain a letter followed by its frequency, in the alphabetical order (from a to z).

Input specification:
Input 1: The input string.

Output Specification:
Return a string representing the frequency counts of characters in the input string.

Example 1:
Input 1: babdc

Output: a1b2c1d1

In the input string, ‘a’ appears once, ‘b’ appears twice, ‘c’ and ‘d’ appear once.

Solution: In C

#include <stdio.h>
#include <string.h>

void printFrequency(int freq[])
    for (int i = 0; i < 26; i++) {
        if (freq[i] != 0) {
            printf("%c%d",i+'a', freq[i]);

void findFrequncy(char S[])
    int i = 0;
    int freq[26] = { 0 };
    while (S[i] != '\0') {
        freq[S[i] - 'a']++;

int main()
    char S[100];
