I did not understood the from the function part and also I had to explore web for the explanation of “LCA”. As LCA is used this Lecture, I think that we should be given a brief knowledge about them.
Also, there is a VERY LOW VOLUME IN ALL LECTURES OF PERSISTENT S.T.
This is a problem because half of the time I have to figure out that what sir is saying.
I searched the web but didn’t got the particular “COT” spoj problem explained.
So, is there any other sources that can explain this concept in form of Lecture of animation
Is there any other source

There are some volume booster extensions for chrome/android etc . you can use that.
