208 PointsI have no clue how to do this question
how do you input even of odds in code? or tell if you can divide by 7
var results: [Int] = []
for n in 1...100 {
// Enter your code below
if in !
// End code
}

54,971 PointsYou will want to use the modulo operator %. If a number is perfectly divisible by another a modulo operation returns zero. For example:
n % 7
equals zero if n is perfectly divisible by 7
n % 2
equals zero if n is perfectly divisible by 2 (and therefore even)
So for this challenge you will want to check if n % 7 == 0 and n % 2 != 0 to see if the number is both perfectly divisible by 7 and odd (not even).

var results: [Int] = []
for n in 1...100 {
if n % 7 == 0 && n % 2 != 0 {
results.append(n)
}
