I have been asked to implement such question:

Given a data file like csv, two columns in it, each line contains “calling No, called No”. Each line actually represents a phone conversion by two person. If A talks to B, and C talks to B, then A and B are friends, A and C are acquaintances. I am asked to look for the person
who has the most acquaintances.

Seems easy enough. Where are you stuck? Do you understand the requirements?
Have you tried doing it on paper to get an idea of what algorithm you might use?
