Option 6 is the correct answer and everyone voting Python is going to cry in the "now optimize this" follow up

JavaScript and I regret nothing. ok I regret the missing built-in heap a little 😅

The missing heap is real. If you go with JS, write a small binary heap once at home so you are not writing it for the first time in the interview.

Java. 9 saal se Java, interview mein bhi Java. Collections.sort ne kabhi dhoka nahi diya 🙏

I interviewed people for years. Nobody serious docks you for Python. They dock you for not knowing what sorted() costs.

Not true on any panel I have sat on. Pick the language you think fastest in. The interviewer is judging the reasoning, not the semicolons.
