Is there a concise, easily calculable way to count the sum of all the paths from the lower left corner of a square of integer size to the upper right corner where you only move up or right in steps of 1 unit, PLUS all the partial paths? i.e. if you have a city with roads in a 10x10 grid (100 intersections/corners) how many shortest paths are there from one corner of the grid to any other intersection or corner on the grid?(adsbygoogle = window.adsbygoogle || []).push({});
