题目链接:http://codeforces.com/problemset/problem/1191/B 题意:类似于麻将,三个一样花色一样数字的,或者三个同花顺就赢了,新抽的能当任何类型,问至少几个. 思路:分类判断即可. AC代码: #include<bits/stdc++.h> using namespace std; bool check(int x,int y,int z) { && abs(y-z) == ) return true; && abs(…

[Codeforces 1191D] Tokitsukaze, CSL and Stone Game(博弈论) 题面 有n堆石子,两个人轮流取石子,一次只能从某堆里取一颗.如果某个人取的时候已经没有石子,或者取完后又两堆石子个数相同(个数为0也算).假如两人都足够聪明,问谁能赢. 分析 贪心考虑,最后局面一定是0~n-1的一个排列.这时谁取谁就输.因此我把a[i]从小到大排序,把a[i]变成i-1,可以计算出取的石子个数\(\sum (a_i-i+1)\),如果是奇数,则先手胜,否则后手胜. 但…

https://codeforces.com/contest/1191/problem/C 一开始想象了一下,既然每次删除都是往前面靠,那么好像就是页数*页容量+空位数=最多容纳到的坐标. 至于为什么呢?好像是每次都会删除干净的原因,从第一页开始考虑,第一页可以容纳到5,这个很显然. 删除之后有2个空位,然后可以容纳到7.再把7也删除,就可以容纳到8. 那么每次就暴力删除特殊元素就可以了,反正最多就是m个. 问题在于翻页的时候不能够简单的curpage++,这样必定翻车.我是直接二分,因为顶多就…
