Given an array. query type 1: Find xor from L to R. query type 2: Update element present at L to X. query type 3: Update element from L to R to X. Would anybody mind explaining how to do this question usingSEGMENT TREE+LAZY PROPAGATION.I am not really getting Idea behind lazy pr...
MZL loves xor very much.Now he gets an array A.The length of Aisn.He wants to know the xor of all (Ai+Aj)(1≤i,j≤n) The xor of an array BisdefinedasB1 xor B2...xor Bn Input Multiple test cases, the first line contains an integer T(no more than20), indicating the number ...
Maximum XOR of Two Numbers in an Array 异或最大值 一、概述 给你一个数组,求出其中任意两个元素异或结果的最大值。 二、分析 O(n^2)的算法不用想,对于每一个元素都和其余所有元素相异或,维护最大值就行。 O(n)的比较难想。我没想出来,看了半天解释。 核心就是,异或这种运算,和乘法有一点点像,知...

C = xor(A,B)performs a logical exclusive-OR of arraysAandBand returns an array containing elements set to either logical 1 (true) or logical 0 (false). An element of the output array is set to logical 1 (true) ifAorB, but not both, contains a nonzero element at that same array ...
Can you solve this real interview question? Maximum XOR of Two Numbers in an Array - Given an integer array nums, return the maximum result of nums[i] XOR nums[j], where 0 <= i <= j < n. Example 1: Input: nums = [3,10,5,25,2,8] Output: 28 Explanati
Hello Codeforces community, I am trying to find the sum of XOR of all pairs in an array, where: n < 3*10^5 and A[i] < 2^60. My algorithm works as follows: For each bit 0 to 59, find how many 0s and 1s there are. Then add (zero_count*one_count*bit_value) to the ...
