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...
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...

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 the alphanumeric...
There is another elegant O(N) solution. The key idea is that when checking each digit in s from left to right, we map each digit to its correct position in t. At position i, if s[i] is mapped to position j in t, then we know for all positions > i with bigger digits than s...
