地址https://leetcode-cn.com/problems/xor-queries-of-a-subarray/ 有一个正整数数组 arr,现给你一个对应的查询数组 queries,其中 queries[i] = [Li, Ri]。 对于每个查询 i,请你计算从 Li 到 Ri 的 XOR 值(即 arr[Li] xor arr[Li+1] xor ... xor arr[Ri])作为本次查询的结果。 并返回一个...
152 Maximum Product Subarray // #152 最大乘积子数组 描述:给定一个整数数组,求子数组的最大乘积。 //#152Description: Maximum Product Subarray | LeetCode OJ 解法1:这题有意思,因为元素都是整数,所以只要不是0,乘积的绝对值只会越变越大。这就造成了一个规律:乘积要么是最大值,要么是最小值,总在两极。

It was encoded into another integer array encoded of length n - 1, such that encoded[i] = arr[i] XOR arr[i + 1]. For example, if arr = [1,0,2,1], then encoded = [1,2,3]. You are given the encoded array. You are also given an integer first, that is the first element...
Given an integer n, return its complement. 题意:求十进制转为二进制后反码的十进制值。 思路: 对十进制数对应的二进制数每一位进行取反,然后放入结果对应的位置中。 遍历二进制的每一位: for(int i=0;(1<<i)<=n;i++){ } 1. 2.
As this problem is about splitting subarrays, we can do it with DP. Say, if the problem is about partitioning the set into M subsets. What do we do? I guess it's then a combinatorial problem, anyway, not mine to worry about. 代码1 // Code 1 解法2:省点空间。 // Solution 2: ...
