Tailing problem

as this was so confused plz explain the tailing process with 23 and 44 tiles

@karthik1989photos,

Imagine you have a floor of size n × m and you are given tiles of size 1× m.
Now you can either place the tiles vertically. Where a tile can be either place vertically,meaning it will only occupy a cell of width 1 and a complete height of M

Eg. If you have n = 2 and m = 2 then you’ve got 2 possible ways which are

1] Either place 2 tiles vertically
2] Or place 2 tiles horizontally

Here n=2 and m=3

Another example:
