Magicaldrome String

index.js

/**
 * 
A Magicaldrome String is a string of characters that reads
the same forward and backward when characters are read in groups of
two and the groups of two are always read from left to right.

For example, "abcdcdab" is a
  Magicaldrome String because the first two characters are the same as the
  last two characters in the string, namely "ab"; and the 3rd and 4th
  characters from the left are the same as the 4th and 3rd characters from
  the right, namely "cd".


  Keep in mind:                     
• The characters in the inputString can be rearranged in any way                                            
• There can be multiple Magicaldrome Strings in the same inputString from different rearrangements                                                      
• The inputString.length will always be a multiple of 4                                            
• 1 <= inputString.length <= 250
