3,536 PointsHow to check if a number is a multiple of 7?
I'm trying this, but It's not working. HELP PLEASE
var results: [Int] = []
for n in 1...100 {
// Enter your code below
if (n % 2 != 0) && (n/7 is Int) {
results.append(n)
}
// End code
}

I was able to get this to pass by using the modulo(%) operator a second time, like this:
var results: [Int] = []
for n in 1...100 {
// Enter your code below
if (n % 2 != 0) && (n % 7 == 0) {
results.append(n)
}
// End code
}
Since it needs to be divisible by 7, there should be no remainder when divided, so the % operator works well.
Happy coding!

Bummer! Make sure you are performing logical checks in the condition of the if statement

I've been writing JS for 5 years and still make simple mistakes like this. Happens to the best of us.
