Five people meet and exchange handshakes. If exactly 3 of the
people each shake hands with 3 people, and if 1 people shakes hands
with 1 other person. Then what is the least number of handshakes that
could have been exchanged?
3 people shake hands ... 3*2/2 = 3
1 person shakes hand with another = 1
Remaining one shakes hands with another one = 1
i would say 5
