• 模拟+贪心 URAL 1804 The Machinegunners in a Playoff


    题目传送门

    题意:A队和B队踢球,已知一场比赛A和B的得分情况,问A最小再得几分就能胜利还有最多能的几分还能给B队一丝翻盘的希望。规则如下:

        1. 总分数相等的情况下,在客场得分高的获胜,如果还相等,那么两者都可能获胜

        2. 总分数高的获胜

    分析:首先假设给出home的分数,A的记为x1, B的记为y1。当x1 >= y1时,最小值x2 == 0,因为y2 == 0,否则先补上x2,使得x1 + x2 == y1 + 0,在考虑客场的因素是否还要+1。至于最大值也是先补全(x1 + x3 == y1 + 30) 然后再考虑客场因素是否-1。away的同理。代码写得冗长,我也没时间精简了。

    代码:

    #include <cstdio>
    #include <iostream>
    #include <algorithm>
    #include <cstring>
    #include <vector>
    using namespace std;
    
    const int N = 1e2 + 10;
    const int INF = 0x3f3f3f3f;
    string s;
    
    int main(void)	{
    	int T;	scanf ("%d", &T);
    	getchar ();
    	while (T--)	{
    		int x1 = 0, y1 = 0, x2 = 0, y2 = 0, x3 = 0;
    		getline (cin, s);
    		int len = s.length ();
    		int c = 0;
    		if (s[26] == 'h')	{
    			int k = 44;
    			while (k < len && s[k] >= '0' && s[k] <= '9')	x1 = x1 * 10 + s[k++] - '0';
    			bool flag = false;
    			for (int i=k; i<len; ++i)	{
    				if (s[i] < '0' || s[i] > '9')	{
    					if (!flag) continue;
    					else	break;
    				}
    				else	{
    					flag = true;
    					y1 = y1 * 10 + s[i] - '0';
    				}
    			}
    			if (x1 > y1)	{
    				x2 = 0;
    			}
    			else if (x1 == y1)	{
    				x2 = 0;
    				if (x2 < y1)	x2++;
    			}
    			else if (x1 < y1)	{
    				x2 = y1 - x1;
    				if (x2 < y1)	x2++;
    			}
    
    			x3 = y1 + 30 - x1;
    			if (x3 > y1)	x3--;
    			x3 = min (x3, 30);
    			cout << x2 << " " << x3 << endl;
    		}
    		else	{
    			int k = 44;
    			while (k < len && s[k] >= '0' && s[k] <= '9')	x1 = x1 * 10 + s[k++] - '0';
    			bool flag = false;
    			for (int i=k; i<len; ++i)	{
    				if (s[i] < '0' || s[i] > '9')	{
    					if (!flag) continue;
    					else	break;
    				}
    				else	{
    					flag = true;
    					y1 = y1 * 10 + s[i] - '0';
    				}
    			}
    			if (x1 > y1)	{
    				x2 = 0;
    			}
    			else if (x1 == y1)	{
    				x2 = 0;
    			}
    			else if (x1 < y1)	{
    				x2 = y1 - x1;
    			}
    
    			x3 = y1 + 30 - x1;
    			x3 = min (x3, 30);
    			cout << x2 << " " << x3 << endl;
    		}
    	}
    
    	return 0;
    }
