多遍历几下

#include<bits/stdc++.h>
using namespace std;
int cha[9];
int main(){
    for(int i = 1;i <= 8;i++){
        int maxx = -1,minx = 0x3f3f3f3f;
        for(int j = 1;j <= 3;j++){
            int t; cin >> t;
            maxx = max(maxx,t);
            minx = min(minx,t);
        }
        cha[i] = maxx - minx;
    }
    int maxn = -1,minn = 0x3f3f3f3f;
    for(int i = 1;i <= 8;i++){
        maxn = max(maxn,cha[i]);
        minn = min(minn,cha[i]);
    }
    int S_index = maxn - minn;
    cout << S_index;
    return 0;
}
