异或门（英語： Exclusive-OR gate ，簡稱 XOR gate ，又稱 EOR gate 、 ExOR gate ）是数字逻辑中实现逻辑异或的逻辑门，功能见右侧真值表。若两个输入的电平相异，则输出为高电平（1）；若两个输入的电平相同，则输出为低电平（0）。

Exclusive or, exclusive disjunction, exclusive alternation, logical non-equivalence, or logical inequality is a logical operator whose negation is the logical biconditional. With two inputs, XOR is true if and only if the inputs differ (one is true, one is false). With multiple inputs, XOR is true if and only if the number of true inputs is odd.

2017年4月24日 · 本文介绍了一种解决The Great XOR问题的有效算法。 该问题要求找到满足特定条件的整数的数量，通过对输入数值的二进制表示进行分析，利用位运算技巧来快速得出答案。

2017年6月24日 · 在探讨Python实现LeetCode题解2429-Minimize XOR的细节之前，我们先了解一下XOR（亦称异或）操作。XOR是按位逻辑运算符之一，其运算规则是两个对应位值相同则结果为0，不同则结果为1。

2022年12月18日 · We need to count all numbers whose XOR with \(n\) produces a greater value. The definition of the bitwise XOR is, that the resulting bit is always 1 if the bit at the same position in both variables are different. To get a feeling of how the XOR operation affects the numbers, lets have a look at the first values of \(n\) in binary notation:

Given a long integer , count the number of values of satisfying the following conditions: where and are long integers and is the bitwise XOR operator. You are given queries, and each query is in the form of a long integer denoting . For each query, print the total number of values of satisfying the conditions above on a new line.

Strategy: observe\analyze bit by bit - DISCRETE THINKING. The idea is like this: if we can XOR any bit in original number X to make that bit into 1 from 0, then any bits following that bit don't matter; and we go check bit by bit. This is also the sln in editorial.

2024年7月31日 · In this HackerRank The Great XOR problem solution we have given Q queries and each query is in the form of a long integer denoting X. for each query we need to print the total number of values of A satisfying the conditions given below.
