This technical problem asks the reader to write a Python function that will sum all of the integers in a given list. An example input and output are provided.
About this solution: This solution correctly sums a list of integers. However, it is not very robust - for example, it would not work if the input was not a list of integers. Additionally, the function does not have any documentation to explain what it does or how to use it.

This problem asks the user to write a function that takes in a list of integers and returns the sum of the integers that are divisible by 3. An example input and output are given.
About this solution: The candidate's solution correctly solves the problem. They iterate through the list and add the numbers divisible by 3 to a sum variable. They then return the sum variable. This is a solid solution that is easy to understand.
