Rotate Array | Arrays | MEDIUM
Problem Link: https://www.geeksforgeeks.org/problem... Hey everyone! 👋 In this video, we'll learn how to rotate an array to the left (counter-clockwise) by d steps in C++, using an in-place algorithm. 🌟 The array is considered circular, so after the last element, the first element will appear again, effectively looping the array. 🔁 Approach 🛠️: We'll use a popular technique called reverse segments to rotate the array efficiently: Reverse the entire array. 🔄 Reverse the first n-d elements (where n is the size of the array). 🔄 Reverse the last d elements. 🔄 This method works in O(n) time complexity and requires O(1) space, making it optimal for large arrays. 🚀 💻 Code & Solution: Check out the solution code in the pinned comment below.
