James submitted a Comment to Problem 3077. Big numbers, least significant digits

If I'm reading the problem statement right, I think either the answer to test case 2 should be 867 (123^3 = 1860867.) or n=2 (123^2=15129).

Hah! Great catch. It's fixed now, but you still get a like for being so sneaky...

I'm glad you enjoy my problems. If there are large numbers in the test suite, it means there's a simple formula you can use to solve it, rather than a brute force approach. (My daughter just hacked into my account again to ask for help...go ahead and try my newest problem!)

Just fire up MATLAB on a VAX system after starting a photo file if you're THAT paranoid. :-)

The only thing I'd add to the problem description is that while all rows must be unique, and all columns must be unique, a row can equal a column and the matrix can still be "solved." Other than that, good problem.
