Recently, I have been searching for some articles about "Smaller to larger" technique on Google, but ended up finding nothing really useful (only the first 2 pages mention about it but they are all about Sack(dsu on tree) :> ...).
So could you guys show me some good documents about that technique and provide me as many as problems you guys have come across during your coding journey? <3
P/s: or share your way of understanding and applying this technique, if you could <3.
Thanks so much and have a great day <3.
The only "document" you need https://mirror.codeforces.com/blog/entry/44351
Can you suggest anything else? Because that article doesn't focus on explaining the smaller_to_larger I think.
Nobody can help me ? :(
What exactly don't you understand?
Could you suggest me some problems of this type?
Problems in Arpa's tutorial are enough
Some people call this technique Sack or dsu on tree. Arpa's blog doesn't explain the technique but shows some ways to code it. I think people that don't know HLD may have a hard time understanding why the technique is fast.
Try to understand the codes, there are also a bunch of questions answered on comments.
Do you think dsu on tree and Smaller to larger is not the same :>
