Compile a list of all square integers below 10,000, not terminating by zero, such that erasing their two last digits creates a new square number.
I get the following that meet the conditions of the problem:
121
144
169
196
441
484
961
1681
Probably not what you intended but I suppose any of the two-digit squares also fit since by erasing the last two digits you're left with just 0.
