给你一个长度为 n 的整数数组 nums 。 考虑 nums 中进行 按位与（bitwise AND）运算得到的值 最大 的 非空 子数组。

You are given an integer array nums of size n. Consider a non-empty subarray from nums that has the maximum possible bitwise AND.

下标从 0 开始、长度为 n 的数组 derived 是由同样长度为 n 的原始 二进制数组 original 通过计算相邻值的 按位异或（⊕）派生而来。 特别地，对于范围 [0, n - 1] 内的每个下标 i ：

Given an integer array arr, return the number of distinct bitwise ORs of all the non-empty subarrays of arr. The bitwise OR of a subarray is the bitwise OR of each integer in the subarray. The bitwise OR of a subarray of one integer is that integer. A subarray…

给定一个非负整数 numRows，生成「杨辉三角」的前 numRows 行。 在「杨辉三角」中，每个数是它左上方和右上方的数的和。   示例 1: 输入: numRows = 5 输出: [[1],[1,1],[1,2,1],[1,3,3,1],[1,4,6,4,1]] 示例 2: 输入: numRows = 1 输出: [[1]]   提示:

Given an integer numRows, return the first numRows of Pascal's triangle. In Pascal's triangle, each number is the sum of the two numbers directly above it as shown:   Example 1: Input: numRows = 5 Output: [[1],[1,1],[1,2,1],[1,3,3,1],[1,4,6,4,1]] Example…

你有两个果篮，每个果篮中有 n 个水果。给你两个下标从 0 开始的整数数组 basket1 和 basket2 ，用以表示两个果篮中每个水果的交换成本。你想要让两个果篮相等。为此，可以根据需要多次执行下述操作：
