/* You will be given two positive integers, a and b (a<=b), separated by a newline.

 For each integer n in the inclusive interval [a,b]:
   If 1<=n<=9, then print the English representation of it in lowercase. That is "one" for 1 , "two" for 2, and so on.
   Else if n>9 and it is an even number, then print "even".
   Else if n>9 and it is an odd number, then print "odd".
