Provide a correct Python 3 solution for this coding contest problem.
Print all combinations which can be made by $k$ different elements from $0, 1, ..., n-1$. Note that we represent $0, 1, ... n-1$ as 00...0001, 00...0010, 00...0100, ..., 10...0000 in binary respectively and the integer representation of a combination is calculated by bitwise OR of the selected elements.
Constraints

Input
The input is given in the following format.
