大佬，求救，怎么改，通过不了

#include<stdio.h>

int main()
{
    int n,i,max,sum = 0;
    scanf("%d",&n);
    int a[n];
    
    for (i = 0; i < n; i++) {
        scanf("%d",&a[i]);
        sum += a[i];
    }
    
    for (i = 1; i < n; i++) {
        max = a[0];
        if (a[i] > max)
            max = a[i];
    }
    
    sum = sum - max;
    
    printf("%d\n",sum);
    
    return 0;
}
