Jul 2, 2024 · Table of Content. Approaches to print a given matrix in spiral form: [Naive Approach]: Using Simulation by Visited Matrix – O (m*n) time and O (m*n) auxiliary space. [Space Optimized Approach]: Using Boundary Traversal – O (m*n) time and O (1) auxiliary space.
Jul 19, 2022 · Given the order of the matrix N and M, and a source location (X, Y), the task is to find all the coordinates of the matrix in order when visited in clockwise spiral order((i.e. East-> South-> West-> North).
Spiral Matrix. Medium. Given an m x n matrix, return all elements of the matrix in spiral order. Example 1: Input: matrix = [[1,2,3],[4,5,6],[7,8,9]] Output: [1,2,3,6,9,8,7,4,5] Example 2: Input: matrix = [[1,2,3,4],[5,6,7,8],[9,10,11,12]] Output: [1,2,3,4,8,12,11,10,9,5,6,7] Constraints: m == matrix.length. n == matrix[i].length.
Mar 30, 2022 · Create a spiral matrix of N*M size from given array - GeeksforGeeks. Last Updated : 30 Mar, 2022. Given two values M and N, fill a matrix of size ‘ M * N ’ in a spiral (or circular) fashion (clockwise) with given array elements. Examples: Input: M = 4, N = 4, arr = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16] Output: 1 2 3 4. 12 13 14 5. 11 16 15 6.
Jun 3, 2020 · We can imagine that the spiral consists of an ordered set of boundaries or horizontal and vertical segments. Observation 1: Each next boundary or segment is one size shorter...
Aug 26, 2023 · The Spiral Matrix problem is a well-known algorithmic challenge that involves traversing a 2D matrix in a spiral order. This means you start at the top-left corner of the matrix and move through its elements in a spiral pattern, going right, down, left, up, and then again right, and so on. Let’s dive into a […]
Jun 23, 2023 · Spiral Order Matrix I. FAQ Q.1: What is the time and space complexity of the recursive approach? Ans: The time and space complexity of the recursive approach is O(N * M) and O(1). Q.2: How to traverse the matrix in an anti-clockwise direction? Ans: The idea is the same.
Given a 2-dimensional matrix, write a program to print matrix elements in spiral order. We can imagine spiral traversal as an ordered set of matrix segments with horizontal and vertical boundaries, where both boundaries are reduced by one at each step.
