Truth behind 0ms Leetcode Submissions | Hack | WeekendWithMIK

Did someone really solve a LeetCode problem in 0ms ? 😳

If you’ve ever seen a LeetCode submission with a 0ms runtime and thought “how is that even possible?”, this video has your answer.
Spoiler : it’s not magic… it’s a clever hack. But also ? It’s not as cool as it sounds.

I will break down how people are faking 0ms submissions on LeetCode using a tiny C++/Python trick. From atexit() to overwriting internal files, we’ll show you how it works, why it’s misleading, and what it actually teaches us about competitive coding.

🚨 Watch till the end to understand the full picture — and why this “hack” isn’t worth it.

🔥 Key Highlights in This Video:
✅ What is display_runtime.txt
✅ How atexit() is used to manipulate results
✅ Why 0ms is NOT real performance
✅ What this means for LeetCode and the community
✅ Examples in both C++ and Python
✅ Should you use it? (Spoiler: NO)
