Given a dictionary, output all word pairs where both words share all their letters except the last two, which are distinct and reversed.

Notes:
  - use a reasonable dictionary of your choice
  - potential word pairs are: "ear, era" ; "revies, revise" ; "burglaries, burglarise"
  - "shear, era" is not a valid pair because "she" != "e"
  - "bell, bell" is not a valid pair because the last two letters are not distinct
  - this will be benchmarked
  - do *NOT* e-mail to ask for clarifications on this question. Make reasonable assumptions and justify them in a README if you feel the need

Submission insructions:
  - Send e-mail to jobs@citrusbyte.com
  - Subject should be "<month> <year> from citrusbyte.com"
  - Attach your resume in pdf or plaintext format
  - Attach a file named yourfirstname_yourlastname-filter.tar.gz with code in any language that does the following:
