How to rotate array java
WebNow here our task is to rotate array by one in a cyclic manner. It is one of the basic operations on the array but in many cases, it comes shady. So, learning how to do it makes our tasks easy. You can consider the below example to know what we are going to do. Input: array [] = {1, 2, 3}/before rotation Output: array [] = {3, 1, 2}/after rotation. WebOutput: The time complexity for the rotation of the matrix will be O(n*n) and the space complexity will be O(1) because we are not using extra space to rotate the matrix..
