LogicalOperators.swift quiz

If someone could help me that would be great. I don't really understand how to find out if n is odd.

Thank you.

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

for n in 1...100 {
    if n % 3 == 0 && n % 7 == 0 {
        results.append(n)
    }
}

Hi Israel,

If n is odd, n % 2 != 0

There is a remainder if you divide n by 2.

I hope that helps.

Steve.
