My issue

why my answer is coming wrong?

My code

#include <stdio.h>

int main(void) {
    int T;
    scanf("%d", &T);
    for (int t = 0; t < T; t++) {
        int N; 
        scanf("%d", &N);
        int max_height = 0;
        for (int i = 0; i < N; i++);
{
        int height;
        scanf("%d", &height);
        if (height > max_height)
{
            max_height = height;
        }
    }
    printf("%d\n", max_height);
 }
    return 0;
