Problem description Enter a decimal number n to convert it to the R-binary output.

Input data contains multiple test instances, each containing two integer n (32-bit integers) and R (2<=r<=16, r<>10).

Output outputs the converted number for each test instance, with one row for each output. If R is greater than 10, then the corresponding number rules refer to 16 binary (for example, 10 is represented by a, and so on).

Sample Input7 2 23 12-4 3

Sample Output111 1b-11
