Sample Solution:

Swift Code:

func test_nums(array_nums: [Int]) -> Bool {
    var p = 0
    var q = 0
    
    for x in 0..<array_nums.count {
        if array_nums[x] == 1 {
            p += 1
        } 
        else if array_nums[x] == 3 {
            q += 1
        }
    }
    
    return p > q
}

print(test_nums(array_nums: [1, 3, 1]))
print(test_nums(array_nums: [1, 3, 1, 3, 2]))
print(test_nums(array_nums: [3, 3]))
 

Sample Output:

true
false
false
