Solution: Rotate Array

Understand how to rotate an integer array to the right by k positions efficiently using the two pointers technique. This lesson teaches an in-place approach that reverses segments of the array to achieve the rotation without extra space. You will learn to normalize rotation steps, perform segment reversals with two pointers, and analyze the time and space complexity of the solution, enabling you to implement similar array manipulation problems confidently.

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 ...
