采用数组
#include<stdio.h>
int main() {
    int n;
    scanf("%d", &n);
    int arr[n];
    for (int i = 0; i < n; i++) {
        scanf("%d ", &arr[i]);
    }
    int max = arr[0], min = arr[0];
    for (int j = 0; j < n; j++) {
        if (arr[j] > max) max = arr[j];
        if(arr[j] < min) min = arr[j];
        }
    printf("%d", max - min);
    return 0;
}
