Solution: Rotate Array

Understand how to rotate an integer array to the right by k steps using an in-place method with two pointers. This lesson teaches a three-step array reversal strategy that efficiently shifts elements without extra space, achieving linear time complexity. Learn to normalize rotation steps and apply two-pointer swaps to restore correct order in constant space.

Statement

Given an integer array, nums, shift its elements to the right by k positions. In other words, rotate the array to the right by k steps, where k is non-negative.

Constraints:

  • 11 \leq nums.length 103 ...
