Grokking the Coding Interview Patterns in C++

Longest Increasing Path in a Matrix

Explore how to determine the length of the longest strictly increasing path in a matrix by moving up, down, left, or right. Learn to apply dynamic programming strategies in C++ to solve this problem efficiently, preparing you for coding interviews that require optimization and pathfinding skills.

We'll cover the following...

Statement

You are given an m×nm × n matrix of integers. Your task is to determine the length of the longest strictly increasing path within the matrix.

A path is defined by consecutively moving from one cell to another adjacent cell. From any cell, movement is allowed only in four directions: up, down, left and right.

Diagonal movement is not allowed. You also cannot move outside the matrix boundaries (no wrap-around).

A path is considered increasing if each ...
