Sample Solution:

Swift Code:

func no25(array_nums: [Int]) -> Bool {
    var num_ctr2 = 0
    var num_ctr5 = 0
    
    for num in array_nums {
        if num == 2 
        {
            num_ctr2 += 1
        } 
        else if num == 5 
        {
            num_ctr5 += 1
        }
    }
    return num_ctr2 == 0 || num_ctr5 == 0
}

print(no25(array_nums: [1, 4, 3]))
print(no25(array_nums: [1, 2, 3, 4]))
print(no25(array_nums: [1, 3, 5]))
print(no25(array_nums: [2, 5]))
 

Sample Output:

true
true
true
false
