描述

Consider an ordered set S of strings of N (1 ≤ N ≤ 31) bits. Bits, of course, are either 0 or 1.

This set of strings is interesting because it is ordered and contains all possible strings of length N that have L (1 ≤ L ≤ N) or fewer bits that are '1'.

Your task is to read a number I ( 1 ≤ I ≤ sizeof(S) ) from the input and print the Ith element of the ordered set for N bits with no more than L bits that are '1'.

输入

Multiple test cases.

For each case, there is a single line with three space separated integers: N, L, and I.

Input

Multiple test cases.

For each case, there is a single line with three space separated integers: N, L, and I.

Output

For each case, output a single line containing the integer that represents the I-th element from the order set, as described.
