The key is to write the code efficiently and neatly and you need to write algorithm also along with comments to explain the code. Interact as much as possible with the mentor.

After this round 25 students were selected for P.I.

Round 3:Technical Round 1

Then he asked me to improvise the approach of the question given in group fly round, I wasn’t able to do that,
