Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following example:
[77, 999, 855, 10, 56, 121, 801]
Solution: [77, 999, 121]
Reason: 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 instance: [237, -89, -844, 805, -121, -46, -589, 345, -369, 174, -461, -343, 203, 80, -922, -748, -89, -29, -636, -210, 763]
Student:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
