Discussion of Problem 1073. Square Country

Good Point
Posted by Seyyed Mehran Kholdi 26 Apr 2008 00:41
There exists a proof by Lagrange, that 4 square are enough to display any number and it's a direct answer.
It's a kind of Number Theory problem. I find it very useful because there is just 2 or 3 conditions you should check.
Good Luck
