Square-Sum Puzzle

January 16, 2018

I don’t watch a lot of television, but the YouTube channel Numberphile is one of the places I am careful not to miss. Numberphile recently had an episode called “The Square-Sum Puzzle” that makes a good exercise:

Rearrange the numbers from 1 to 15 so that any two adjacent numbers must sum to a square number.

Your task is to write a program to solve the Numberphile square-sum puzzle. When you are finished, you are welcome to read or run a suggested solution, or to post your own solution or discuss the exercise in the comments below.
