给你一个二维整数数组 squares ，其中 squares[i] = [xi, yi, li] 表示一个与 x 轴平行的正方形的左下角坐标和正方形的边长。 找到一个最小的 y 坐标，它对应一条水平线，该线需要满足它以上正方形的总面积 等于 该线以下正方形的总面积。 答案如果与实际答案的误差在 10-5 以内，将视为正确答案。 注意：正方形 可能会 重叠。重叠区域只 统计一次 。   示例 1： 输入： squares = [[0,0,1],[2,2,1]] 输出： 1.00000 解释： 任何在 y =…

You are given a 2D integer array squares. Each squares[i] = [xi, yi, li] represents the coordinates of the bottom-left point and the side length of a square parallel to the x-axis. Find the minimum y-coordinate value of a horizontal line such that the total…

给你一个整数数组 nums。

You are given an integer array nums. A subarray is called balanced if the number of distinct even numbers in the subarray is equal to the number of distinct odd numbers. Return the length of the longest balanced subarray.   Example 1: Input: nums = [2,5,4…

请你实现三个 API append，addAll 和 multAll 来实现奇妙序列。 请实现 Fancy 类 ：

Write an API that generates fancy sequences using the append, addAll, and multAll operations. Implement the Fancy class:

有一条无限长的数轴，原点在 0 处，沿着 x 轴 正 方向无限延伸。 给你一个二维数组 queries ，它包含两种操作：

There exists an infinite number line, with its origin at 0 and extending towards the positive x-axis. You are given a 2D array queries, which contains two types of queries:

给你一个长度为 n 的整数数组 nums 和一个整数 k。

You are given an integer array nums of length n and an integer k. You must select exactly k distinct non-empty subarrays nums[l..r] of nums. Subarrays may overlap, but the exact same subarray (same l and r) cannot be chosen more than once. The value of a…

给你一个整数数组 nums 和一个整数 target。

You are given an integer array nums and an integer target. Return the number of subarrays of nums in which target is the majority element. The majority element of a subarray is the element that appears strictly more than half of the times in that subarray.…
