In this task you will be given a list of integers. You should only return an integer if the first digit is the same as the last digit in the number. If an integer has a single digit, then it should be returned. If there are no integers that start and end with the same digit then an empty list ("[]") should be returned.
One example: [77, 999, 855, 10, 56, 121, 801]
Solution is here: [77, 999, 121]
Explanation: The integers 77, 999, and 121 are the only integers in the input list that start and end with the same digit.

Now, solve this: [-510, 132, -579, -624, 882, 838, 964, -421, -487, -971, -787, 25, 888, -878, 20, 215, -620, 117, -611, -836, -449]
Solution:
[838, -787, 888, -878]
