In a certain code language, STREAMLING is written as CGTVUHOJMN. How will the word PERIODICAL be written in that language?

The letters in the first half and second half of the word are written in the reverse order and in the group of letters so obtained, each letter in the first half is moved two steps forward while that in the second half is moved one step forward, to get the code. Thus, we have: PERIODICAL => PERIO/DICAL => OIREP/LACID => QKTGR/MBDJE.
