Solution: Rotate Array

Explore how to rotate an array to the right by k positions efficiently in-place using the two pointers technique. This lesson guides you through reversing segments of the array to achieve the rotation without extra memory, understanding each step's logic and time-space complexity tradeoffs.

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 ...
