William submitted a Comment to Problem 60826. Identify Similar Rows in a Matrix Based on Sequence of Non-zero Elements

Christian, I think that this problem is fundamentally okay, except that test problem #1 has an incorrect result, and it is a bit ambiguous about what the result *should* be in the case that the input in a zero matrix. In the latter case, I think you are right, but since the test of similarity only involves the matrix elements that are not zero, and there are none, I suppose there could be some room for disagreement. Certainly, the only possible correct answers would be either the entire matrix or the empty matrix.

William submitted a Comment to Problem 60783. Convert integers from base 10 to proper primary notation

Paragraph 3 says "5 can be represented as pp, pxx and pxmm ...", but if I am not mistaken, the value of 'pxmm' is 2. Could you have meant 'pxxm'?

William submitted a Comment to Problem 60790. Implement Shor's algorithm

I see. But I guess that doesn't work when you try to run the test in the ScratchPad to check your solution. It just complains that there is no function named modexp().

Christian, where does the modexp() function that is used in the test problems come from?

William submitted a Comment to Problem 60795. Ohm’s Law - Calculate Resistance

This formula is incorrect. It calculates power rather than resistancee.
