You want to perform the combo on your opponent in one popular fighting game. The combo is the string ss consisting of nn lowercase Latin letters. To perform the combo, you have to press all buttons in the order they appear in ss. I.e. if s=s="abca&qu
You are given two positive integers aa and bb . In one move, you can change aa in the following way: Choose any positive odd integer xx (x>0x>0 ) and replace aa with a+xa+x ; choose any positive even integer yy (y>0y>0 ) and replace aa with
A. Add Odd or Subtract Even 题意：给两个数xy，每次对x加上一个奇数或者减去一个偶数，问从x变到y的最小操作次数。 分析：判断一下x和y的奇偶性讨论一下就可以了。 #include <bits/stdc++.h> using namespace std; int main(){ int t; cin>>t; while(t--){ int

A 选正奇数 增加，正奇数减少，首先判断两个数的大小关系。看是该增加还是减少，然后答案显然只有0,1,2。 int main(){ int t = read(); while(t--){ ll a,b; a = read();b = read(); if(a == b) puts("0"); else if(a < b){
题目链接：Three Integers 简要题意： 给出 \(a, b, c\) 满足 \(a \leq b \leq c\)。 你可以随便选择其中一个数，使这个数 \(+1\) 或 \(-1\)。 假设最后操作完 \(a\) 为 \(A\)，\(b\) 为 \(B\)，\(c\) 为 \(C\)。 你需要使 \(A | B\) 且 \(B | C\)，并最小化操作次数。 输出操作次数和 \(A,
