Project Euler 141 - Investigating progressive numbers, n, which are also square

Official link: https://projecteuler.net/problem=141

Thought Process

Sometimes i'm not exactly sure how Project Euler grades their problems, this problem is very similar to Problem 518, which is a 20% problem, and this problem has smaller constraints so it actually ended up being easier... oh well I got level 6 with this as my 150th problem!
