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 origi
Given an arraynumssorted in non-decreasing order, and a numbertarget, returnTrueif and only iftargetis a majority element. Amajority elementis an element that appears more thanN/2times in an array of lengthN. Example 1: Input: nums =[2,4,5,5,5,5,5,6,6], target =5 Output:true E...
You can rotate the array by x = 0 positions (i.e. no rotation) to make nums. Example 4: Input:nums = [1,1,1]Output:trueExplanation:[1,1,1] is the original sorted array. You can rotate any number of positions to make nums. Example 5: Input:nums = [2,1]Output:trueExplanation:...
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...

heapify - create a heap from an array of elements, needed for heap_sort heap_sort() - take an unsorted array and turn it into a sorted array in-place using a max heap note: using a min heap instead would save operations, but double the space needed (cannot do in-place). Sorting ...
Output: false Check if a given string is a valid palindrome but ignore characters other than Uppercase, Lowercase and Digits (alphanumeric). The comparison is case-insensitive. The empty string is defined as a valid palindrome. First step, it is easy to check if any character is one of th...
