This problem deals with finding the sum of all integers in a list that are greater than or equal to 10. An example input and output are provided.
About this solution: The candidate's solution correctly solves the problem. They iterate through the list, checking if each integer is greater than or equal to 10. If it is, they add it to the sum. This is a solid approach.

This problem asks the user to write a function that takes in a list of integers and returns the sum of all the even numbers in the list. An example input and output are given.
About this solution: This solution correctly returns the sum of the even numbers in the list. The approach is to use a list comprehension to create a new list consisting only of the even numbers in the original list, and then to use the built-in sum function to sum up the numbers in the new list. This is a concise and elegant solution.

This Python function removes all the vowels from a given string.
About this solution: The candidate's solution is optimal because it uses a for loop to iterate through the string and check if each character is a vowel. If it is not a vowel, it is added to the new string.

Given a set of distinct integers, this function will print the size of the largest subset such that no two integers in the subset sum to more than k. For example, given the input [ 1, 2, 3, 4, 5] and k = 6, the output would be 3.
About this solution: The candidate's solution is correct and demonstrates a level of completeness. The approach is sound and the time and space complexity are both optimal.

Given a string of words, this function will return the length of the longest word. For example, given the input string "The quick brown fox jumps over the lazy dog", the function will return 6, since "quick" is the longest word in the string.
About this solution: This solution correctly finds the length of the longest word in a string. It splits the string into a list of words, then loops through the list to find the longest word. This is a good approach.
