CodeSignal [47/60] isMAC48Address

Problem:

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.

 

Example

• For inputString = "00-1B-63-84-45-E6", the output should be
  isMAC48Address(inputString) = true;
• For inputString = "Z1-1B-63-84-45-E6", the output should be
  isMAC48Address(inputString) = false;
• For inputString = "not a MAC-48 address", the output should be
  isMAC48Address(inputString) = false.

-Summary-

1. data 를 '-' 으로 나누어 splitdata list 에 넣어준다.

2. split 된 data의 문자각각이 숫자 0-9 사이 또는 영문자 A-F 사이에 있는지 체크한다. 

3. 모든 체크후 pass하면 True 값 return 아닐경우 False return.
