  numbers = [5,1,13,2,7,9,10]

1. Use each to return an array with all of the elements from the numbers array that have two or more digits.
2. Refactor the code you implemented for #1 above to use find_all instead of each.
3. Use each to find all of the elements from the numbers array whose squares are odd. (Example: 5 would be returned because 5^2 = 25 and 25 is odd. 10 would not be returned because 10^2 is 100 and 100 is even.
4. Refactor the code you implemented for #3 above to use find_all instead of each.
