    1:03:44 you don't necessarily have to distribute 3's and 5's and multiply to 2's , you can always multiply last 2 with remaining factors .

    On problem E I missed the first line "You are given an undirected graph consisting of n vertices and n edges". I kept trying to solve the problem for a general graph and was thinking "why is this so much harder than F". Thanks for the stream
    I think you can skip the binary search on F by just increasing the size of whichever outer range has the smaller max.

    Codeforces : is it rated?
    TH-cam : why only 360p?

    How many years have you been coding? I started learning html and javascript for web development and python for back-end. Any tips you could give me that would help me develop my skills more effectively?

      C didn't require special knowledge, just being careful, you should be able to get that. D requires knowing about prime factorization, E requires knowing some graph theory, and F requires knowing about RMQ or segment tree. So whether you should get those just depends on how much experience you have.
