Spiral matrix properties. At first starting from the first row, print the whole content and then follow the last column to print, then the last row, and so on, thus it prints the elements in a Intuition: The problem is about collecting numbers in a matrix in a defined "spiral order". Use direction arrays dr and dc to represent right, down, left, and up movements. . We print the elements of the outer boundary first, then move inward to print the elements of the inner boundaries. To understand Spiral Matrix from first principles, let's break down the concept into fundamental components and then explore how they come together For 2D-Array, common solution patterns include: Perform a BFS/DFS Search through the 2D Array DFS: The problem statement asks us to return all elements of the matrix in spiral order, which means we will start from the top left corner and move towards right, then down, then left, and then up. Jul 17, 2025 · We can print the matrix in a spiral order by dividing it into loops or boundaries. The first output equals mat [0] [0]. Suppose we have a matrix and we have to print the matrix elements in a spiral way. Jul 12, 2025 · Approach: The idea is to simulate the spiral traversal using direction arrays to keep track of the movement (right, down, left, up) and change direction when we hit the boundary or an already filled cell.
