题目链接:http://codeforces.com/contest/451/problem/C 解题报告:三个球队之间一共有n场比赛,现在已经进行了k场,不知道每个球队的胜场是多少,如三个球队的胜场分别为a,b,c,那么已知的是: |a - b | = d1 |b -c | = d2 输入n,k,d1,d2,要你判断有没有可能让三个球队最后的胜场数相同. 只要分四种情况就可以求出a,b,c分别是多少,然后判断是不是满足: n % 3 == 0 a,b,c都小于n / 3 a >= 0 &&…

解题报告 http://blog.csdn.net/juncoder/article/details/38102391 题意: n场比赛当中k场是没看过的,对于这k场比赛,a,b,c三队赢的场次的关系是a队与b队的绝对值差d1,b队和c队绝对值差d2,求能否使三支球队的赢的场次同样. 思路: |B-A|=d1 |C-B|=d2 A+B+C=k 这样就有4种情况,各自是: B>A&&C<B B>A&&C>B B<A&&C<B…

A - Game With Sticks 题目的意思: n个水平条,m个竖直条,组成网格,每次删除交点所在的行和列,两个人轮流删除,直到最后没有交点为止,最后不能再删除的人将输掉 解题思路: 每次删除交点所在的行和列,则剩下n-1行和m-1列,直到行或列被删完为止,最多删除的次数为min(n,m),删除min(n,m)后剩余的都是行或者列(注意行与行,列与列之间不可能有交点).只需要判断min(n,m)的奇偶性. #include <iostream> #include <vector&…
