Listen to each assistant's responses to the following instruction, and give each a score out of 100 and an explanation for the score. Here are some additional guidelines: * Do not award bonus points. * If the instruction includes additional context from which the response should be generated, deduct points if the response includes details not found within the provided context. * The assistants should not be making assumptions about the intent of the question. * If the instruction asks for results in a specific format, e.g. JSON, 50% of the score should be whether or not the assistant produced the correct format. * Award points for effort and problem formulation when the instruction is related to solving mathematical equations or coding. Respond in format "[assistant number]. [score]/100 - [explanation] Instruction: Write a Swift function that accepts two arrays of integers and returns an array containing their element-wise sum. Assistant 1's response: Here's a Swift function that accepts two arrays of integers and returns an array containing their element-wise sum: ```swift func sumArrays(_ array1: [Int], _ array2: [Int]) -> [Int] { return zip(array1, array2).map(+) } // Example usage: let array1 = [1, 2, 3, 4, 5] let array2 = [6, 7, 8, 9, 10] let result = sumArrays(array1, array2) print(result) // Output: [7, 9, 11, 13, 15] ``` Assistant 2's response: Sure, here's the function you're looking for: ```swift func arraySum(_ array1: [Int], _ array2: [Int]) -> [Int] { let minLength = min(array1.count, array2.count) let maxLength = max(array1.count, array2.count) var result = [Int]() for i in 0.. minLength { remainingArray = Array(array1[minLength..(_ a: [T], _ b: [T]) -> [T] { var result = [T]() for i in 0.. [Int] { var result = [Int]() for i in 0..(_ a: T, _ b: T) -> T { var result: T = [] for i in 0.. [Int] { var result = Array(repeating: 0, count: array1.count + array2.count) for i in 0..
1. 100/100 - The provided function is correct, concise, and uses Swift's `zip` and `map` functions to achieve the desired result. It properly calculates the element-wise sum of two arrays.
2. 95/100 - The function works correctly and handles cases where the input arrays have different lengths. However, it could be more concise by using Swift's built-in `zip` function like Assistant 1 did.
3. 50/100 - The function has a generic type parameter `` which is unnecessary for this task, as we only need to work with integers. Additionally, the addition operation inside the loop (`a[i] + b[i]`) will not compile because the compiler cannot infer that `+` can be applied to elements of type `T`. The rest of the code structure is reasonable, but the incorrect use of generics makes the solution unusable without modification.
4. 85/100 - The provided function is mostly correct but assumes that both input arrays have the same length. If the input arrays have different lengths, it will cause an out-of-bounds error when accessing array elements. Otherwise, the code is clean and easy to understand.
5. 40/100 - The provided function attempts to use a generic type `T`, but the constraint `ArrayType` does not exist in Swift. This results in a compilation error. Also, the function assumes that both input arrays have the same length, which may not always be true. Without fixing these issues, the function is unusable.
6. 60/100 - The provided function initializes the `result` array with an incorrect count (sum of counts of both input arrays), causing extra zeros at the end of the resulting array. However, the core logic of iterating through the indices and calculating the element-wise sum is correct. With proper initialization of the `result` array, the function would work as expected.
