Consider the following simplified P2P application. There are 2n peer nodes and, during the time in question, no peers join or leave the swarm. It takes a peer 1 unit of time to upload or download a file chunk, during which time it could only do one or the other. Initially, one peer has the entire file and the others have nothing.

a. If the requested file only have 1 chunk, what is the minimum amount of time for all the peers to have the entire file?

b. The same question when the requested file have 2 chunks.
