# Number of total ways to reach to the top stair…[Cprogm] FcukTheCode

Steve Waugh and Mark Waugh are sitting at the bottom of their tree house and debating in how many ways they can jump up the stairs on the tree and reach the tree house.
Because Steve Waugh is older than Mark Waugh, he can jump one, two, or three stairs in one step while Mark Waugh can jump just one or two stairs in one step.
