`gen` feature allows 0 for `MAXIMUM_DIGITS`

[nus-pe-bot]

When given 0 for MAXIMUM_DIGITS field, it generates all zeroes. This behaviour shouldn't exist as there should be no numbers with 0 maximum digits.

Perhaps there should be checks to verify if it is 0?

It's true that when I wrote the boundary condition check, I only thought about excluding those cases that would crash the system, and didn't consider the case where the operand was all 0, thanks for mentioning it ：D
