38B - Chess 思路:懂点象棋的规则就可以,看看哪些点可以放马. 代码: #include<bits/stdc++.h> using namespace std; #define ll long long int main() { ios::sync_with_stdio(false); cin.tie(); string s,t; cin>>s>>t; ]-,y=s[]-'; ]-,b=t[]-'; ; ;i<=;i++) { ;j<=;j++)…

893A Chess For Three 思路: 直接模拟即可,第一盘永远是A与B开始 代码: #include <bits/stdc++.h> using namespace std; #define _for(i,a,b) for(int i=(a); i<(b); ++i) #define _rep(i,a,b) for(int i=(a); i<=(b); ++i) int n,num,a[4]; int main() { ios::sync_with_stdio(fals…

题意: 移动最少的步数,使得所有的棋子在同一颜色的格子中. 每次一个棋子只能向左或者向右移动一步,不能移到有棋子的格子中. 思路: 枚举全黑和全白的情况. 对于每一个需要移动的棋子,它移动到的位置一定是从1开始第一个可以移动的位置,不交叉移动,保证了步数最小. 代码: #include <stdio.h> #include <string.h> #include <algorithm> using namespace std; ; int v[N],g[N]; int…

题目: 题意:输入一个整数n,接着输入2*n个数字,代表2*n个选手的实力.    实力值大的选手可以赢实力值小的选手,实力值相同则都有可能赢.    叫你把这2*n个选手分成2个有n个选手的队伍.    问你是否有一种分法让一个队伍必定会赢. 分析:就像田忌赛马,我们要让第一个队更多的选手赢,全赢输出YES,否则输出NO. 所以我们只需要让第一个队最弱的选手能胜过第二个队最强的选手,我们就可以保证第一个队一定会赢. 代码: #include <bits\stdc++.h> using nam…
