• there will be no handshakes at all.i will try to explain as....let elder decreasing series is 5,4,3,2,1
  5 can only shake hands with his youngers like 4,3,2,1 only but condition is there that only to younger ones elder can shake hand so why 4,3,2,1 shake hands with 5 bcz he is elder than them.so no hands will shake .same consideration is done for other members then result will be 0 handshakes
