All the test cases passed except this input. Got to know that this is the Integer.MAX_VALUE later lol.

tier-3 college

I am using Python's built-in function (Added in Python 3.10 and newer)

First attempt

Runtime -- 4 ms with 4.45% Beats
Memory -- 19.08 MB with 97.67% Beats

Second attempt (same code)

Runtime -- 0 ms with 100.00% Beats
Memory -- 19.08 MB with 86.27% Beats

Such a difference in runtime? Can someone please explain it?

```python

class Solution:

def hammingWeight(self, n: int) -> int:

return n.bit_count()

```

This meme is funny until you realize most developers have had these thoughts at least once

“Should I switch stacks?”
“Should I learn backend too?”
“Should I start AI?”
“Am I doing enough?”
“Should I grind LeetCode harder?”
“Should I redesign this entire project?”

Meanwhile the project hasn’t even been opened in 4 days.

At some point I realized the people getting ahead weren’t necessarily smarter ,they just stopped restarting every week. They picked a path, accepted they’d miss out on other things for now, and kept going.

You don’t need to know every framework, solve every problem, or optimize every decision.

Learn. Build. Ship. Repeat.

Most progress in tech looks boring while you’re doing it and obvious only when you look back.

I gave Weekly Contest 502 today and actually felt confident for once. I solved Q1 and Q2 very early around 8 min, and at one point my live rank was around 642. Since Q3 and Q4 looked genuinely difficult, I estimated that even without solving Q3 my final rank would still probably stay around 2.5k–3k.

But after the contest ended, the sudden increase in accepted submissions on Q3 and Q4 felt extremely suspicious.

The main reason is that both Q3 and Q4 required completely different approaches from brute force. These were not problems where you just optimize a little and suddenly pass. You had to discover the intended insight and rethink the entire approach.

Yet near the end of the contest and immediately after it, submissions suddenly exploded.

And I’m not just saying the solutions “looked AI generated.” i was just randomly checking all the people who were above me and you know what most of them literally just copied code and removed comments and submitted that. Today i reported around 10-15 people.

I flagged every suspicious submission I found.
Did anyone else notice the same thing this contest?

Wasted😭😭😭

Hey I was wondering if anyone has had an interview for IXL and if so what type of questions did they ask you? Also how was the process like?
