Solution: Rotate Array

Explore how to rotate an array in place by k positions using the two pointers technique. This lesson teaches you to reverse segments of the array step-by-step for an efficient O(n) time and O(1) space solution, helping you master array manipulation patterns for coding interviews.

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 ...
