    I'm glad you liked them!

    The intended solution for F is just segment tree (not a straightforward application tho).

    Problem C can be solved with binary search and hashing (I thought that one would had more accepted solutions tbh).

    And problem L is really hard. I don't think I'm able to explain it haha. However, an editorial with detailed solutions will be posted soon :3
