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
ans!!!
