Write a function named place$\_$ladders$($board$,$ NUM$\_$SQUARES,NUM$\_$LADDERS$)$ that adds three ladders to the board from the task above. The ladders should be placed randomly. If the cell has a ladder top represent it with $$L$$ and ladder bottom with $$l$.$ Note that we use this representation for snakes and ladders so that when the board is displayed on the screen, the player can clearly see which cells have ladder top and ladder bottom.

Input: The current status of the board, number of squares and number of ladders.

Output: A table that represents the $5$x$10$ board with snakes and ladders placed on the board in specific places.

For example:

$>>>$ board $=$ initialise$\_$board $($board$,$NUM$\_$SQUARES$)$

$>>>$ board $=$ place$\_$ladders$($board$,$NUM$\_$SQUARES,NUM$\_$LADDERS$)$

$>>>$ print$\_$board$($board$)$
