To find the sum of a list of integers, simply add all the numbers in the list together. In the example given, the sum would be 15.
About this solution: The candidate's solution is correct and uses the built-in sum function, which is an optimal solution.
Find the sum of all elements in a list. This can be done in Python by iterating through the list and adding each element to a total.
About this solution: This solution is correct and efficient. The candidate has used the built-in sum function, which is the most efficient way to sum a list.
This problem involves writing a function that takes in a list of integers and returns the sum of those integers. An example input and output are given in the problem statement.
About this solution: This solution is complete and solves the problem. The approach is straightforward and easy to understand.
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.
This problem asks the user to return a list of integers that are divisible by 3. The input is a list of integers, and the output is also a list of integers.
About this solution: The candidate's solution is correct and uses a list comprehension, which is an efficient way to solve the problem.
Write a Flask route that returns the sum of a list of integers.
About this solution: This solution is correct and demonstrates a level of completeness. The candidate has used the sum() function, which is an optimal solution. The candidate has also used a one-liner, which is also optimal.
This technical problem deals with writing a function that returns the sum of the elements in an array. An example input is given as [1, 2, 3, 4, 5], and the expected output is 15.
About this solution: This is a great solution! It is concise, readable, and uses a built-in function, which is likely to be more efficient than a custom solution.
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.
