Learn and practice the In-place Reversal of a Linked List, Stacks, and Matrices patterns to solve coding interview problems.

Educative-99 in Python: Accelerate Your Coding Interview Prep

Interviewers want to be sure that the candidate is comfortable manipulating linked lists, arrays, and data structures based on them, such as stacks and matrices. This module will provide the practice you need to review the concepts and techniques needed to solve common problems involving these data structures.

Basic Data Structures

# Statement

Given an $m\times n$ matrix, return an array containing the matrix elements in spiral order, starting from the top-left cell. 

**Constraints:**

- $1\leq$ `matrix.length` $\leq 10$
- $1\leq$ `matrix[i].length` $\leq 10$
- $-100\leq$ `matrix[i][j]` $\leq 100$
