https://leetcode.com/problems/divide-two-integers/ Divide two integers without using multiplication, division and mod operator. If it is overflow, return MAX_INT. 解题思路: 很讨厌做这种类型的题目,一来不熟悉,二来要注意的地方很多,比如溢出问题,计数的边界,只能硬着头皮上。题目要求不能使用乘法、除...
Given two integersdividendanddivisor, divide two integerswithoutusing multiplication, division, and mod operator. The integer division should truncate toward zero, which means losing its fractional part. For example,8.345would be truncated to8, and-2.7335would be truncated to-2. Returnthequotientafter ...

C. Bitwise Balancing 首先(x|b)≥(x&c) 所以可以从高位到低位贪心的确定 a 该位取什么值,接下来就是大力分类讨论 using ll = long long; void solve() { ll b, c, d; std::cin >> b >> c >> d; ll a = 0, res = 0; for (int i = 60; i >= 0; i--) { int x = b >...
