Sample Solution:

Swift Code:

func num15(array_nums: [Int]) -> Bool {
    for x in 0..<array_nums.count 
    {
        if array_nums[x] != 2 && array_nums[x] != 5 
        {
            return false
        }
    }
    return true
}

print(num15(array_nums: [1, 2, 5, 4]))
print(num15(array_nums: [2, 5, 2, 5]))
print(num15(array_nums: [2, 5]))
 

Sample Output:

false
true
true
