贪心，主要是排序的方法，自己想了好久，没想出来，看了题解，恍然大悟，原来还能这样写，又新学到了一个技能点O(∩_∩)O哈哈~

#include<iostream>#include<algorithm>#include<string>#include<vector>#include<cstdio>using namespace std;string strs[55];bool cmp(string a, string b) {    return a + b > b + a;}int main() {    int n;    while(scanf("%d",&n) == 1 && n) {        for(int i = 0; i < n; ++i) {            cin >> strs[i];        }        sort(strs, strs + n, cmp);        for(int i = 0; i < n; ++i) {            cout << strs[i];        }        cout << endl;    }    return 0;}
