My issue

what is the reason for runtime error

My code

#include <stdio.h>

int main() {
    int T;
    scanf("%d", &T); 
    
    while (T--) {
        int N;
        scanf("%d", &N);
        
        int A[N];             
        int freq[11] = {0};   
        
        for (int i = 0; i < N; i++) {
            scanf("%d", &A[i]);
            if (A[i] >= 1 && A[i] <= 10) {  
                freq[A[i]]++;
            }
        }
        
        int max_frequency = 0;
        for (int i = 1; i <= 10; i++) {
            if (freq[i] > max_frequency) {
                max_frequency = freq[i];
            }
        }
        
        int min_moves = N - max_frequency;
        printf("%d\n", min_moves);
    }
    
    return 0;
}
