  • If the remainder on diving battle day by 3 is 1, E and D participate.
  • if the remainder on dividing battle day with 3 is 2, D and M participate. 

Input Format
The first line will contain an integer Y.

Output Format
Report which of the two houses are fighting on the Yth day.
(i.e. you will have to print one of the three battles ME, ED or DM)
