A for loop is a programming language statement which allows code to be repeatedly executed.
The syntax is

for ( < expression_1 > ; < expression_2 > ; < expression_3 > )    < statement >

expression_1 is used for intializing variables which are generally used for controlling the terminating flag for the loop.expression_2 is used to check for the terminating condition. If this evaluates to false, then the loop is terminated.expression_3 is generally used to update the flags/variables.

A sample loop is

for(int i = 0; i < 10; i++) {    ...}

In this challenge, you will use a for loop to increment a variable through a range.

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

Output Format
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".

Note: [a,b] = { x ∈ Z | a <= X <= b } = {a, a+1 , a+2, a+3, ... b}

Sample Input
8
11

Sample Output
eight
nine
even
odd
