Solution: Rotate Array

Explore how to rotate an integer array to the right by k positions using a three-step in-place reversal strategy. This lesson teaches you to use two pointers to reverse segments of the array efficiently, achieving rotation without extra space and in linear time.

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\leq 10^3

  • 231-2^{-31} \leq ...
