Problem statement : STONES Problem - CodeChef
My code is:

#include <string.h>
#define MAX 101
int j[26*2];
int s[26*2];
int main(void) {
	int t, i;
	scanf("%d", &t);
	while(t--){
	    char stone[MAX], jewel[MAX];
	    scanf("%s", jewel); scanf("%s", stone);
	    for(i = 0; i < 26*2; i++){
	        j[i] = 0; s[i] = 0;
	    }
	    for(i = 0; i < strlen(jewel); i++){
	        if(jewel[i] <= 'Z')
	        j[jewel[i] - 'A'] = 1;
	        else
	        j[jewel[i] - 'a' + 26] = 1;
	    }
	    for(i = 0; i < strlen(stone); i++){
	        if(stone[i] <= 'Z')
	        s[stone[i] - 'A'] = 1;
	        else
	        s[stone[i] - 'a' + 26] = 1;
	    }
	    int count = 0;
	    for(i = 0; i < 26*2; i++){
	        if(s[i] && j[i])
	        ++count;
	    }
	    printf("%d\n", count);
	}
	return 0;
}

I cant figure out what’s wrong in this simple code. Thanks.

According to the question if a character occurs in stone multiple times and it occurs in jewel even once , the answer would be the frequency of that character in stone. So you have to store the frequency of the characters rather than just checking the occurrence. For example

Jewel - a
Stone - aa

Answer - 2

Right, Thankyou.
