Q4 with the duplicate pairs is tricky. I got that same one and my first hashmap approach was wrong because I was double-counting (i, i) pairs when both elements are identical.
Yeah exactly, that's where I lost points I think. Did you end up passing?
Reply to @kchen92Got through, but barely. Think I was around 720ish. Took 3 weeks for them to move me to a phone screen.
Q3 matrix rotate is a classic gotcha. Easy to mess up the indexing if you do it in-place. I just copied to a new matrix and it worked fine.
Same, I did a fresh matrix for rotate. Didn't want to risk a bug with in-place during the test.
What role/level did you apply for? Trying to figure out if the OA difficulty scales at all.
Saw similar Q1 and Q4 a few months back. The problems seem to rotate but a lot of the core patterns repeat. Good luck, hopefully you cleared the bar.
The ID upload thing is annoying. Mine kept failing to load on the first try, burned like 3 minutes before I could even start.
