Spiral rotation of matrix

WebGiven an n x n 2D matrix, write a program to rotate the matrix by 90 degrees in the anticlockwise direction. The program should rotate the matrix 90 degrees without using extra space. In other words, we have to perform the rotation by modifying the 2D matrix directly. Note that this is an excellent problem to learn problem-solving using loops and … WebMar 15, 2024 · Scala Style: Matrix Rotation and Spirals .Post -5 by vikrant Medium Write Sign up Sign In vikrant 19 Followers Follow More from Medium Darius Foroux Save 20 Hours a Week By Removing These 4...
