Ladder-on-Box Puzzle Solver for HP 15c

Description:This program solves the classic problem of a ladder resting on a square box. This program will solve the problem in two ways: (1) Plugging and chugging or (2) using the 15c SOLVE function. This is for anyone who is ever in dire need of calculating the distance between the tip of the ladder down to the top of the box on which the ladder is resting. In all honesty, this is just a trivial program for one very particular type of problem – unless you really need to find out how high you can climb on a ladder of length L resting on a square box of height c. However, it does two things for me (and maybe you as well): helps get experience coding with the SOLVE function, and gives some exposure/intuition on how to use it to find the roots of a function in general with the 15c.
