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: [-336, -475, 998, -779, 300, -366, 908, 767, 168, 653, 112, -485, 255, -219, 834, -371, 187, -961, -555, 511, -171, -61]
Solution:
[767, -555, -171]
