Coding Challenge – Reverse Polish Calculator

 Reverse polish notation is a system in which the operators follow the operands.  For example 2 3 + would mean that 2 and 3 should be summed together. It does not need any parenthesis as long as the operators work on a fixed number of operands. Anyways, the coding challenge today is to create a […]

Coding Challenge – Bodies of Water

Problem: Write a program that first takes an integer N giving both the X and Y size, and then N number of lines. Each line will contain N space-delimited characters, 0, 1, or 2. These characters represent altitude on the map. Zero means water. First, find the bodies of water. A body of water is […]
