The chef got a new rabbit and he is going to train him so that he can perform for him whenever he needs entertainment. The chef teaches k types of jumps to the rabbit. Each jump has definite length L units. The rabbit does not have any brains he will use any type of jump he feels like at any point of time. He is placed on a very long mat and starts at 0 unit. The chef wants to know in how many ways he can perform his jumps and cover exactly N units of distance.
If the rabbit jumps exactly L units then N has to be a multiple of L..........
let us say L*m = N.......
then for every jump the rabbit has k types.........
and he has to jump m times to cover N units!!
thrfr, he has k choices for 1st jump, k choices for 2nd jump and so on (upto m times).. k * k * k * k * k........... = km = k N/L
