My issue

Where I have to change my code

My code

#include <stdio.h>

// Function to compute the GCD of two numbers
long long gcd(long long a, long long b) {
    if (b == 0)
        return a;
    return gcd(b, a % b);
}

// Function to determine if all elements of the array can be made equal
void canMakeEqual(int n, long long arr[]) {
    long long resultGCD = arr[0];
    int hasZero = 0;
    
    // Check if there's a zero in the array and calculate the GCD of all elements
    for (int i = 0; i < n; i++) {
        if (arr[i] == 0) {
            hasZero = 1;
        }
        if (i > 0) {
            resultGCD = gcd(resultGCD, arr[i]);
        }
    }
    
    // If there's a zero in the array, it's always possible to make all elements equal to zero
    if (hasZero) {
        printf("YES\n");
    } else if (resultGCD > 1) {
        printf("YES\n");
    } else {
        printf("NO\n");
    }
}

int main() {
    int T;
    scanf("%d", &T);
    
    while (T--) {
        int N;
        scanf("%d", &N);
        
        long long arr[N];
        for (int i = 0; i < N; i++) {
            scanf("%lld", &arr[i]);
        }
        
        canMakeEqual(N, arr);
    }
    
    return 0;
}
