I'm at college in the UK and studying A-Level Maths and Further Maths. Our teacher has given us a problem, just for fun, not actual homework, which I'm interested in solving. Please let me make it clear that I want no answers to this problem; just some pointers in the right direction please, as answers would ruin the fun.
The question is: Are there any square repeat numbers? (A repeat number being any number, which is made up of a repetitive pattern of other numbers, eg., 592592 or 365345365345 or 999 or 100100 or 2222 etc........)
I've written a computer program to try to solve this with brute force checking of every number, but I wasn't sure that this was working correctly and it gave no results up to the limit of language's highest-precision numeric data type.
