Imagine you have a big square sheet of paper and you want to cover it completely with smaller squares. But, you don't want to overlap any of the smaller squares or leave any empty spots on the big square. That's the covering problem!
It's like when you play with blocks and you have to cover a square with smaller blocks, but you have to make sure there are no spaces in between them. It's like playing a puzzle game where you have to place pieces on a board, but you have to make sure they fit together perfectly and there are no gaps left.
This covering problem is important in many areas, like when you want to find the best way to pack boxes in a truck, or to design a floor plan for a house that uses the space efficiently without leaving any empty areas.
So, the covering problem is all about finding the best way to cover a large area with smaller pieces, without leaving any gaps or overlapping any parts.
