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 M rows and N columns, find the number of ways to reach the cell with coordinates (i, j) from the starting cell (0, 0) under the condition that you can only travel one step right or one step down.
