Answer 1

#include <stdio.h>

    int main () {
    int n;
    scanf("%d",&n);
    char a[n];
    char b[n];
    int i,j,k,sum;
    int flag = 1;
    for(i=0;i<n;i++) {
        scanf("%d",a[i]);
    }
    for(i=0;i<n;i++) {
        for(j=1;j<a[i];j++) {
            if(a[i] % j == 0) {
                flag = 0;
                break;
            }
        }
        if(flag) {
            sum += a[i];
        }
        b[i] = sum;
        sum = 0;
    }
    for(k=0;k<sizeof(b);k++) {
        printf("%d\n",b[k]);
    }
    
    return 0;
