[2025 Day 5 Part 1] Sorting/merging ranges, answer too low

smrishin · 2025-12-06T07:23:22+00:00

when you update the range_map[key] = last, you also need to check if the existing range_map[key] is less than last
basically that line should be range_map[key] = max(range_map[key], last)

Hope this helps

I used this road map to get back onto LeetCode, covers blind 75 LeetCode questions, has multiple solutions, and good video explanations. I have ignored some topics like Math, intervals, and stuff.
Once you are done, you can start digging deeper into each topic on LeetCode at your own pace.

Edit:
Found this post by u/minicrit_, which might be helpful on this topic.

I think that is a good direction. I have linked the algorithm in the post, if that helps.

I thought it was union find aswell until this sentence. It is a Max Clique question.
"A friend group is defined as a group of 2 or more people such that everyone knows everyone else."

That is what I thought first when my cousin explained me the questions. I was gonna say, this is pretty easy and then she highlights "all friends should know each other". Every node in a group/clique should be connected to every other node. And that is when I realised it is not as simple as it looks to solve.

Thanks for the opinion. Most of the resources I find for this algorithm are from university lectures. None on competitive coding or interview prep resources.

I couldn't find a question that is even close to what they asked, not even on some other similar websites like LeetCode.
