Problem

Write a program called nums_between_chars that reads the following input and produces the following output.

Input

The first line of the standard input contains a single integer N. The second line contains a sequence of exactly four characters with no spaces between them. Each character is a letter of the Latin alphabet or a digit.

Output

On separate lines of the standard output, the program must print the product of N with each number found in the sequence.

If the sequence contains only letters, the program must print "N/A" (without the quotes).

Constraints

0 ≤ N < 100
