Given two positions in a 2-D matrix, say (x1, y1) and (x2, y2) where x2>=x1 and y2>=y1. Find the total number of distinct paths between (x1, y1) and (x2, y2). You can only move in right direction i.e. positive x direction (+1, 0) or in up direction i.e. positive y direction (0, +1) from any given position.
Example: If the given coordinates are (3,3) and (5,5), the number of distinct paths are 6 : one going through 3,5 ; one going through 5,3 and four going through 4,4. -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
