The function should take a list of integers as input and return the sum of the even integers in the list.
About this solution: This solution is optimal because it uses a generator expression to filter the list and sum the even numbers. This is optimal because it is a single pass through the list, and it does not require any additional memory. It is also very readable.
This problem deals with finding the sum of all integers in a list that are greater than or equal to 10. An example input is given, as well as the expected output.
About this solution: The candidate's solution correctly solves the problem and returns the sum of the integers that are greater than or equal to 10. The candidate's approach is to iterate through the list and add the integers that are greater than or equal to 10 to a sum variable. This is a valid approach and the candidate's solution is complete.
This Python function takes a list of integers as input and returns the largest number in the list.
About this solution: The candidate's solution correctly finds the largest number in the list. The candidate could have used the built-in max() function to find the largest number in the list.
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 Python code snippet returns the sum of integers that are greater than or equal to 10 in a list.
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 that would work well for this problem.
Given a list of integers, this Python function will find the sum of the even numbers in the list.
About this solution: This solution correctly finds the sum of all even numbers in the given list. It uses a simple for loop to iterate through the list, checking if each number is divisible by 2 (i.e. is even), and if so, adding it to the running total. This is a straightforward and effective solution.
This Python class implements a stack using a list. The stack supports the following operations: push, pop, size, and isEmpty.
About this solution: This solution is complete and solves the problem. The approach is straightforward and easy to understand.
This problem is about writing a function that returns the sum of the elements in a list. If the list is empty, the function should return 0.
About this solution: This solution correctly returns the sum of the elements in the list. However, it is not robust and will not work if the list is empty. The function should check for an empty list and return 0 if the list is empty.
