What are bad examples of challenges?

Question

I'm sure some of you came across bad examples of challenges. Post them here so the challenge creators won't create challenges these kind of challenges anymore.

Answer 1

I consider bad challenges as those challenges that aren't focused on the language but mental arithmetic or some weird logic puzzle e.g. where they reverse and re-reverse some bool/boolean multiple times.

I mean WTF...?? These kind of problems don't occur in real life. If they do, then you have encountered bad code and shouldn't get used to these kind of code.

My 2 cents.

Answer 2

@Thanh Le: This is the exact reason why I don't even challenge. I tried once when I first started and was presented with a bunch of pure math questions with an unrealistic time to answer. I figured from then on my time was better spent learning to code then memorizing a bunch of random answers that will never help me progress as a programmer. So yeah. Thats why I never even bother.

Answer 3

Yeah completely agree. These type of questions make challenges into just a memory game. The advantage goes to the player who has encountered the question before and can remember the correct answer.

Answer 4

When a typo occurs error. In real life, the IDE doesn't allow you compile the code.

Answer 5

I remember only 1 I still realy hate - about <center> tag in html.
It's out of date.Nobody should use it or even know or think about it.Its just a trash in your memory.
