求个最大值

AC代码：

#include<cstdio>

#include<climits>

using namespace std;

int main() {

    int n,x;

    int maxn;

    while(scanf("%d",&n) != EOF) {

        maxn = INT_MIN;

        while(n--) {

            scanf("%d",&x);

            if(maxn < x)

                maxn = x;

        }

        printf("%d\n",maxn);

    }

    return 0;

}
