Question: Given a 2-dimensional arrayA[1..m, 1..n], compute the number of ways (paths) of starting at the top-left corner to the bottom-right corner. All moves must go

Given a 2-dimensional arrayA[1..m, 1..n], compute the number of ways (paths) of starting at the top-left corner to the bottom-right corner. All moves must go either right or down. (1) Formulate the recursive relation of the optimal solution;(2) Design a bottom-up algorithm to calculate the number of paths; (3) Analyze the complexity of your algorithm.
