# A media access control address (MAC address) is a unique identifier assigned to network
# interfaces for communications on the physical network segment.

# The standard (IEEE 802) format for printing MAC-48 addresses in human-friendly
# form is six groups of two hexadecimal digits (0 to 9 or A to F), separated by hyphens (e.g. 01-23-45-67-89-AB).

# Your task is to check by given string inputString whether it corresponds to MAC-48 address or not.
