在Java位运算总结-leetcode题目博文中总结了Java提供的按位运算操作符,今天又碰到LeetCode中一道按位操作的题目 Given a range [m, n] where 0 <= m <= n <= 2147483647, return the bitwise AND of all numbers in this range, inclusive. For example, given the range [5, 7], you should return 4. 题意:…
Given a range [m, n] where 0 <= m <= n <= 2147483647, return the bitwise AND of all numbers in this range, inclusive. For example, given the range [5, 7], you should return 4. Credits:Special thanks to @amrsaqr for adding this problem and creatin…

Brief linkFly的<JavaScript-如果...没有方法>中提及如何手写Math.round方法,各种奇技淫招看着十分过瘾,最让我惊叹的是 ~~(x + )) ,完全通过加法和位运算搞定整数的四舍五入.在好奇心的驱使下重温了一下位运算,并对上述公式加以封装得到适合小数的四舍五入方法 function round(v/*alue*/, p/*recision*/){ p = Math.pow(, p>>> ? : p|) v *= p )|) / p } 在开波前…

Given a range [m, n] where 0 <= m <= n <= 2147483647, return the bitwise AND of all numbers in this range, inclusive. For example, given the range [5, 7], you should return 4. 思路: 先找前面二进制相同的位,后面不相同的位相与一定为0. 比如: 1111001 1110011 从0011 - 1001 中间一定会经…
