Problems Involving Grids - 2

Understand how to solve grid traversal problems by applying dynamic programming techniques. Learn to calculate the number of ways to reach a specific cell by moving only right or down in a 2D matrix, using memoization to optimize computations and handle overlapping subproblems effectively.

Problem statement

The problem in this lesson tries to solve the following type of question:

Finding the number of ways to reach from a starting position to an ending position when traveling in specified directions only.

The problem statement is:

Given a 2-D matrix with ...
