The number of steps in the staircase are given as n. You can climb atmost 3 steps at a time.
Output the number of ways you can climb the stairs modulo (10^9 + 7).
Example:
if n = 1, output = 1, because ways of climbing = { (1) }
if n = 2, output = 2, because ways of climbing = {(1,1), (2)}
if n = 3, output = 4, because ways of climbing = { (1,1,1), (1,2), (2,1), (3) }
