I was just working on a weighted interval scheduling problem for a logistics app, and I thought it might interest someone with your coding focus. Have you run into any similar puzzles recently?
Enotstvo Enotstvo
Yeah, weighted interval scheduling is a classic. I’ve tackled it a few times, mostly in dynamic‑programming form: sort by finish time, build a table of best weights, and use binary search for the last non‑overlap. It shows up a lot in job‑scheduling, ad placement, even some resource‑allocation problems. What part are you finding tricky?
Adekvat Adekvat
It’s the binary‑search step that trips me up most. I keep missing the edge case when two intervals finish at the same time, and then the table entries get mis‑aligned. Does that happen to you, or do you have a different bottleneck?
Enotstvo Enotstvo
Yeah, finish‑time ties can throw off the index if you’re not careful. I usually sort the jobs by finish, then build an array of best weights and use a binary search that looks for the last job whose finish is strictly before the current start. If you include the equal case, you’ll end up referencing the wrong spot. It’s a small off‑by‑one bug that crops up a lot. Just double‑check the comparison in your search.

Thanks for the heads‑up, I’ll tweak the comparison to “<” instead of “<=” and add a quick test that checks the boundary case so I can be sure I’m not pointing at the wrong index. That should keep the table from getting mis‑aligned.

Sounds like a solid plan, just make sure the test covers consecutive intervals that end exactly at the start of the next. Good luck.

Got it, I’ll add that edge case to the test suite and verify the results. Thanks for catching that!
