Solution: Rotate Array

Understand how to rotate an array in place by applying the two-pointer technique to reverse array segments. This lesson guides you through normalizing rotation steps and performing three reversals to efficiently shift elements without extra 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\leq 10^3

  • 231-2^{-31} \leq ...
