#190. Reverse Bits Reverse bits of a given 32 bits unsigned integer. For example, given input 43261596 (represented in binary as 00000010100101000001111010011100), return 964176192 (represented in binary as 00111001011110000010100101000000). 题解:移位运算.…
Reverse bits of a given 32 bits unsigned integer. Example 1: Input: 00000010100101000001111010011100 Output: 00111001011110000010100101000000 Explanation: The input binary string 00000010100101000001111010011100 represents the unsigned integer 432615…
public class Solution { public uint reverseBits(uint n) { var list = new List<uint>();//逆序的二进制列表,list[0]是最低位 ) { ; list.Add(cur); n = n / ; } - list.Count; ; i < addzero; i++)//补充到32位 { list.Add(); } list.Reverse(); ; ; i < list.Count; i++) {…
按位操作符只能用于整数基本数据类型中的单个bit中,操作符对应表格: Operator Description & 按位与(12345&1=1,可用于判断整数的奇偶性) | 按位或 ^ 异或(同假异真) ~ 非(一元操作符) &=,|=,^= 合并运算和赋值 <<N 左移N位,低位补0 >>N 右移N位,(正数:高位补0,负数高位补1) >>>N 无符号右移(无论正负数,高位皆补0) <<=,>>=,>>…
