浮点水题hdoj2014这题之前做了很多次错了很多次纪念一番~

#include<stdio.h>int main() {int n;double sum, x, _max, _min;while(scanf("%d", &n)!=EOF) {sum = 0; _max = -1; _min = 1e8;for(int i = 0; i < n; i++) {scanf("%lf", &x);sum += x;if(x > _max) _max = x; if(x < _min) _min = x;}sum = sum-_max-_min;printf("%.2lf\n", sum/(n-2));}return 0; }
