Swift Array Programming Exercises: Test if a given array of integers contains either 2 even or 2 odd values all next to each other

Sample Solution:

Swift Code:

func two_even_odd(array_nums: [Int]) -> Bool {
    for x in 0..<array_nums.count-2 {
        if (array_nums[x] % 2 == 0 && array_nums[x+1] % 2 == 0) || (array_nums[x] % 2 == 1 && array_nums[x+1] % 2 == 1) {
            return true
        }
    }
    return false
}

print(two_even_odd(array_nums: [2, 1, 3, 5]))
print(two_even_odd(array_nums: [2, 1, 2, 5]))
print(two_even_odd(array_nums: [2, 4, 2, 5]))
print(two_even_odd(array_nums: [1, 3, 2, 5]))

Sample Output:

true
false
true
true
