Hard coding solutions

Suppose we have question with single integer as input and the input ranges from 0 to n where n is small.
Is it ok to hard code answer for the inputs in the source code?

Yes. It is completely valid. You can submit your solution as a text file by choosing Text as the submit language in the dropdown menu

If it works, it’s correct :stuck_out_tongue:

but for that we would need to know the input, which isn’t possible(except if you’re in the NSA/CIA/Illuminati)
