if statement problem

Have to use if statement to check the condition to test odd number and multiply of 7, confused the way question worded

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

for n in 1...100 {
    // Enter your code below
    if n % 3 == 0 && n % 3 !=0{
    results.append(n)
    }
    // End code 
}

you are checking for % 3 == 0 and % 3 != 0, which doesnt make sense. nothing would satisfy that. what you should be checking for is % 2 != 0 to determine odd numbers and % 7 == 0 to determine multiples of 7.

if n % 3 == 0 && n % 3 !=0

This in my opinion is really hard to read.

if ((n % 3) == 0) && ((n % 3) != 0))

What you wrote is very hard to read, writing it this way using proper math rules actually makes it easy for someone to read and it makes sure things are executed correctly.
