Return which contiguous elements of the list sum to K in Swift

Given a list of integers and a number K, return which contiguous elements of the list sum to K.

For example, if the list is [1, 2, 3, 4, 5] and K is 9, then it should return [2, 3, 4], since 2 + 3 + 4 = 9.

func findContiguousElements(lst: [Int], K: Int) -> [Int]? {

for i in 0..<lst.count {

for j in i..<lst.count {

let subList = Array(lst[i...j])

if subList.reduce(0, +) == K {

return subList

}

return nil

}
