Sample Solution:

Swift Code:

func num13(array_nums: [Int]) -> Bool {
    for num in array_nums {
        if num == 1 {
            for num in array_nums {
                if num == 3
                {
                    return true
                }
            }
        }
    }
    return false
}

print(num13(array_nums: [0, 3, 2]))
print(num13(array_nums: [3, 1, 2]))
print(num13(array_nums: [3, 1, 7, 5, 2]))
 

Sample Output:

false
true
true
