# Codechef 6 months Internship 2021

I have also received the mail. Next round is web development using codechef API. According to me those who have solved all questions ( or 4 might be ) are receiving the mail. Like I solved 5.

I have also received the mail for next round today.

Solved 5. Still didnāt get any mail.

Can you share the approach for 4th question?
and they should least unlock the leaderboard.

1. Find LCA using sparse Table. (refer this https://www.youtube.com/watch?v=g48iAXLt5XU)
2. Calculate distance ie ) distance between u and v = distance[u] + distance[v] - 2 * distance[LCA(u, v)].
3. Time Complexity : NlogN (for preprocessing spare table) + q(logN) were q = no of queries.

did exactly like that but each time got TLE.

Did you use fast IO?

yes I did
