Create a function that returns "even" if a number has an even number of factors and "odd" if a number has an odd number of factors.

Examples

factorGroup(33) ➞ "even"

factorGroup(36) ➞ "odd"

factorGroup(7) ➞ "even"

Notes

• You don't need to actually calculate the factors to solve this problem.
• Think about why a number would have an odd number of factors.
