Solution \(2a>n\),一次性结束,直接输出 \(n\) \(a \geq b\),那么一直修即可,直接输出 \(n\) 否则,\(a\) 占弱势,我们考虑用 \(a\) 修一半需要的完整轮次数为 \([(n-1)/2a]\) ,那么这些轮中, \(a\) 修掉的个数为 \([n/2a]a\),而 \(b\) 修掉的个数则是 \([n/2], [n/2a]b\) 中的较小值.计算剩余量然后暴力修即可. #include <bits/stdc++.h> using namesp…

A. Erasing Zeroes Description You are given a string \(s\). Each character is either 0 or 1. You want all 1's in the string to form a contiguous subsegment. For example, if the string is 0, 1, 00111 or 01111100, then all 1's form a contiguous subsegm…

B. National Project 题意:总长度为n的公路进行维修,天气是有规律性的,连续g天的好天气,连续b天的坏天气,必须在好天气进行维护,问至少维护n的一半,那么至少需要多少天 思路:必须是g的整数倍和b的整数倍构成的天数,通过相除,假设g+b是一组,最后尾巴那算作单算 想法:1)这个数必须是g的整数倍和b的整数倍构成的,或者是直接输出n,这个限制条件是题目中没有提到,但是你必须写的 代码: 1 #include<iostream> 2 #include<algorithm&g…
