Iyas likes measuring things, for that he wants to create his own special ruler, he has a wooden stick of length $L$ and wants to draw dashes on the stick so that it works as a ruler, the ruler will also have a precision $P$.
The ruler will consist of multiple lines, there are $L + 1$ main lines, the $i$th of them will have $P$ dashes and number $i-1$ next to the dashes, between those will be other lines consisting of $P-1$ dashes and so on until lines with a single dash are reached (see examples for a clearer idea).
Given $L$ and $P$, print the drawing that should be on the ruler.
