This program finds the longest word in a list of words.
About this solution: The candidate's solution is correct and uses an optimal approach. The candidate correctly uses the built-in function max() to find the longest word in the list. The candidate also correctly uses a lambda function as the key function to determine the longest word in the list.
To find the sum of the elements in a list of integers, simply iterate through the list and add each element to a total.
About this solution: This is a good solution that demonstrates a level of completeness and solves the problem. The approach is straightforward and easy to understand.
Given an array of integers, find the maximum sum of a contiguous subarray. For example, given the array [-2, 1, -3, 4, -1, 2, 1 , -5, 4], the maximum sum of a contiguous subarray is 6 (the sum of the subarray [4, -1, 2, 1]).
About this solution: This is a great solution! The candidate has thought about the problem carefully and has come up with a very elegant solution. The candidate has also provided a clear explanation of how the solution works. Well done!
This problem asks you to return the sum of all the odd integers in an array. For example, if the input array is [1, 2, 3, 4, 5], the output should be 9.
About this solution: This solution is optimal because it uses a generator expression to filter out the even numbers and then sums the odd numbers. This is optimal because it is a one-liner and it is also very readable.
Given a list of integers, the largest sum of non-adjacent numbers can be found by writing a function. The function will take the list as input and return the largest sum possible.
About this solution: The candidate's solution is correct and solves the problem. The approach is to use a dynamic programming approach, which is a good approach for this problem. The candidate could have been more concise in their solution, but overall the solution is correct and solves the problem.
