The task here is to filter a list of integers for only those numbers that have the same first and last digit. If a number is a single digit, it is also to be included. If no such numbers exist, an empty list should be returned. 

Here are the steps to solve the task:
- Loop through each integer in the list.
- Convert the integer to a string because string manipulation is easier.
- For each string, check the first and the last character. If they are the same, keep the integer in the list.
- If the string length is 1, i.e. the integer is a single digit, keep it in the list.
- Go to the next integer in the list.
- If there are no integers that fit the criteria, return an empty list.

Using these guidelines:

Input: [-170, 356, -971, 234, 546, -388, -401, 54, -684, 632, 333, 18, 456, -623, -541, 544, 737, 802, -207, -717, 710]

The output will be: [-170, 544, 737, -717, 710]

This is because -170, 544, 737, -717, and 710 all start and end with the same digit, and all the other numbers do not. Since we don't have any single digit numbers, there is none of it in the result set.<|im_end|>

 Sure, I'd be happy to help! Here's the definition of the task you provided:

Task: Given a list of integers, return a list of integers that start and end with the same digit.

And here's the input list of integers you provided:

[-170, 356, -971, 234, 546, -388, -401, 54, -684, 632, 333, 18, 456, -623, -541, 544, 737, 802, -207, -717, 710]

Now, let me explain the guidelines for this task. We need to check each integer in the list to see if the first digit is the same as the last digit. 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.

Here's how I will solve this task:

Step 1: Check each integer in the list to see if the first digit is the same as the last digit.

Step 2: If an integer has a single digit, then return it.

Step 3: If there are no integers that start and end with the same digit, then return an empty list.

Now, let me apply these guidelines to the input list:

Step 1: Check each integer in the list...

* -170: first digit is 1, last digit is 0, so it does not meet the condition.
* 356: first digit is 3, last digit is 6, so it meets the condition.
* -971: first digit is -9, last digit is -1, so it does not meet the condition.
* 234: first digit is 2, last digit is 4, so it meets the condition.
* 546: first digit is 5, last digit is 6, so it meets the condition.
* -388: first digit is -3, last digit is -8, so it does not meet the condition.
* -401: first digit is -4, last digit is -1, so it does not meet the condition.
* 54: first digit is 5, last digit is 4, so it meets the condition.
* -684: first digit is -6, last digit is -4, so it does not meet the condition.
* 632: first digit is 6, last digit is 2, so it meets the condition.
* 333: first digit is 3, last digit is 3, so it meets the condition.
* 18: first digit is 1, last digit is 8, so it does not meet the condition.
* 456: first digit is 4, last digit is 6, so it meets the condition.
* -623: first digit is -6, last digit is -3, so it does not meet the condition.
* -541: first digit is -5, last digit is -1, so it does not meet the condition.
* 544: first digit is 5, last digit is 4, so it meets the condition.
* 737: first digit is 7, last digit is 7, so it meets the condition.
* 802: first digit is 8, last digit is 2, so it meets the condition.
* -207: first digit is -2, last digit is -7, so it does not meet the condition.
* -717: first digit is -7, last digit is -1, so it does not meet the condition.
* 710: first digit is 7, last digit is 0, so it meets the condition.

Step 2: If an integer has a single digit, then return it...

* 356
* 234
* 54
* 632
* 333
* 737
* 802

Step 3: If there are no integers that start and end with the same digit, then return an empty list...

No integers meet the condition, so the output list will be:

[356, 234, 54, 632, 333, 737, 802]

Therefore, the output list of integers that start and end with the same digit is:

[356, 234, 54, 632, 333, 737, 802]<|im_end|>

You will be given a definition of a task first, then some input of the task.
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.

[-170, 356, -971, 234, 546, -388, -401, 54, -684, 632, 333, 18, 456, -623, -541, 544, 737, 802, -207, -717, 710]
Output:<|im_end|>
