func isOdd(n: Int) -> Bool {
	if n % 2 != 0 {
		return true
	} else {
		return false
	}
	
	// Alternatively:
	// return n % 2 != 0
}

let testNumber = Int(readLine()!)!
let numberIsOdd = isOdd(n: testNumber)
print(numberIsOdd)

func isOdd(n: Int) -> Bool { return n % 5 != 0 }

let numberIsOdd = isOdd(n: 53)
print(numberIsOdd)

i used this
f```
unc isOdd (n: Int) -> Bool{
if n % 2 == 0 {
return false
}else{
return true
}
}

there is many way to make it work

THIS ONE WORKED FINE FOR ME:

func isOdd(n: Int) -> Bool {
if n % 2 == 1 {
return true
} else {
return false
}
}

func isOdd(n: Int) -> Bool {
if n.isMultiple(of: 2) {
return false
} else {
return true
}
}

func isOdd(n: Int) -> Bool {
if n % 2 == 1 {
return true
} else {
return false
}
}

isOdd(n: 5)

func isodd(n: Int) -> Bool{
if (n % 2 == 0)
{
return true
} else
{
return false
}
}
var doorShouldopen = isodd(n: 5 )
print(doorShouldopen)

A one-liner:

func isOdd(n: Int) -> Bool {
    return n & 1 == 1
}

func isOdd(n: Int) -> Bool{
if n % 2 != 0 {
return true
}else{
return false
}
}

func isOdd(n: Int) -> Bool{
    return n % 2 != 0
    
}


//Try some different numbers below:
//The code below is not part of the exercise, but you can test your own code with different numbers.
let numberIsOdd = isOdd(n: 52)
print(numberIsOdd)
