Given an object or an array, return if it is empty. An empty object contains no key-value pairs. An empty array contains no elements. You may assume the object or array is the output ofJSON.parse. Example 1: Input:obj = {"x": 5, "y": 42}Output:falseExplanation:The object has 2...
Given an array nums, return true if the array was originally sorted in non-decreasing order, then rotated some number of positions (including zero). Otherwise, return false. There may be duplicates in the original array. Note: An array A rotated by x positions results in an array B of ...
Hello, LeetCode team 😄 If we go through the examples of the problem and stop at the very first explanation: Explanation:[1,2,3,4,5] is the original sorted array. You can rotate the array by x = 3 positions to begin on the the element of value 3: [3,4,5,1,2]. The definit...
