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: [-329, 974, 278, 991, -492, -156, -482, 178, 624, 238, -600, -488, 55, -530, -680, 90, 652, -466, -766, -376, 870]
Solution:
[55]
