Grokking the Coding Interview Patterns in Go

Introduction to Matrices

Explore essential matrix concepts such as addition, multiplication, transpose, and traversal techniques like row-major and spiral traversal. Understand how to apply these patterns to solve common coding problems involving 2D arrays. This lesson helps you identify matrix-based problems and equips you with conceptual tools useful in image processing, graphics, data analysis, and machine learning contexts.

We'll cover the following...

About the pattern

A matrix is a group of numbers arranged in rows and columns in a rectangular pattern. In computer science, matrixes are represented by 2D arrays with dimensions m×nm \times n, where mm is the number of rows, and nn is the number of columns. Each element in the matrix can be accessed using the array indexes. The first index represents the row, and the second index represents the column. For example, matrix[i][j]matrix[i][j] is an element from the ithi^{th} row and the jthj^{th} column of the matrix.

Matrix transformations are operations performed on matrices that result in a new matrix. There are several types of matrix transformations commonly used in mathematics ...
