HOJ_1302

Feb 02, 2014  |  HOJ  |  Algorithm

今天因为要去江北那点有点事,下午回来又睡了一觉,所以就只刷了一道水题。

昨天晚上九江起了很大的雾,今天中午还没散去,车子在大桥中间的时候,前方和后方的路都看不见了,这种感觉很有意思,好像我们就是行驶在一段凭空出现的道路上。

还是说水题吧。

这道题很简单,就是判断一个数是不是可以拆散成阶乘的和,本来想把可能性都列出来打表的,结果发现还不如用贪心呢,需要注意的是,0的阶乘是1,一定要带上,我就是这样WA了好几次。。。

#include <iostream>
using namespace std;

typedef struct Team{
    char name[100];
    int detail[4][2], correct, penalty;
} Team;

int main(){
    int n, winner = 0;
    Team t[100];
    cin >> n;
    for(int i = 0; i < n; i++){
        t[i].correct = 0;
        t[i].penalty = 0;  //如果把这两个值在结构体内确定的话,clang++是warning,但在HOJ上无法编译
        cin >> t[i].name >> t[i].detail[0][0] >> t[i].detail[0][1] >> t[i].detail[1][0] >> t[i].detail[1][1] >> t[i].detail[2][0] >> t[i].detail[2][1] >> t[i].detail[3][0] >> t[i].detail[3][1];
        for(int j = 0; j < 4; j++){
            if(t[i].detail[j][1] != 0){
                t[i].correct += 1;
                t[i].penalty = t[i].detail[j][0] > 1 ? t[i].penalty + t[i].detail[j][1] + (t[i].detail[j][0] - 1) * 20 : t[i].detail[j][1] + t[i].penalty;
            }
        }
    }
    for(int i = 0; i < n; i++){
        if(t[i].correct > t[winner].correct)
            winner = i;
        else if(t[i].correct == t[winner].correct){
            if(t[i].penalty < t[winner].penalty)
                winner = i;
        }
    }
    cout << t[winner].name << ' ' << t[winner].correct << ' ' << t[winner].penalty << endl;
}
