I recently stumbled upon this screenshot while researching social media on the train. Of course, it was followed by a cascade of spiteful comments, criticizing this fresh programmer’s attempt to solve a classical problem in computer science. The modulus operation.

    Could be easily made 50% space saving by only iffin all odds and return even on else. Maybe one if before to handle overflow to avoid wrong even if over the last if.

      Yeah but then ALL even numbers would be slow to compute because you would have to chain through every odd before you know that 2 is even.

      Depends on the expected distribution of input values

      There’s not a single thing in this universe that cannot be accomplished with enough IF statements… as long as you’ve got infinite time to wait

    I like this bit at the end:

    As a side note, the program is amazingly performant. For small numbers the results are instantaneous and for the large number close to the 2^32 limit the result is still returned in around 10 seconds.
