Hi abhishekredwal
Understand the question properly:
Given a floor of size n x m. Find the number of ways to tile the floor with tiles of size 1 x m
Explanation : There are two ways to place a tile

  1. Horizontally, tile size = 1xm, no problem as you can always place it if a row is empty
  2. vertically, tile size = mx1, you have to check if m<=n i.e atleast m rows are empty

Hope it helps
Please mark resolved if satisfied :slight_smile:
