@premang,
What was not clear? You just have to count the number of ways to tile the floor.
For floor of 4*5, there are two ways to tile it with tiles of 4*1.

  1. Place the first tile vertically and the rest 4 tiles horizontally.
  2. Place the first 4 tiles horizontally and the rest 1 tile vertically.

4.where to complain ?

3rd class explanation(video)

#8

@premang,

Your queries:

  1. Just copy/paste the sample test cases here and I will explain. I currently cannot access them.
  2. If we just give away all the working codes, how will anyone learn.

Your questions:

  1. Because it would be of no use to anyone. You would not benefit anything from copy pasting the code.
  2. What is the difference between them…?? Both are same.
  3. You don’t need to know everything when you are a beginner, just code it by yourself, you will learn about them when necessary.
  4. You are complaining.

@premang,
For 4*7 floor and 1*7 tile, theres only one possible way, keep all tiles vertically.
