What numbers you mean..?

Are [7, 21, 35, 49, 63, 77, 91] right..?

logicalOperators.swift 
var results: [Int] = []

for n in 1...100 {
    // Enter your code below
    if (!(n % 2 == 0) && n % 7 == 0) {
        results += [n]
    }
    // End code 
}

Hey Ronny Setiawan,

Try refactoring your code to make it more readable. You can use the not equals operator instead of reversing the value with the not operator. You can also use the append method to add the number to the results array.

var results: [Int] = []

for n in 1...100 {
    // Enter your code below
    if (n % 2 != 0) && (n % 7 == 0) {
        results.append(n)
    }
    // End code 
}

Good Luck
