iOS repl.it - Functions 3 Challenge Solution

functions3.swift

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)

same here

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

//Do not change the code below.
let testNumber = Int(readLine()!)!
let numberIsOdd = isOdd(n: testNumber)
print(numberIsOdd)

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

I did exactly this code but my console was returning error. After 10min trying to understand I just realised that my B on Bool wasn't in capital letter. Damn

Solution:

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

ha! another one

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

func isOdd(n: Int) -> Bool {
// Number not divisible by 2
if n % 2 != 0 {
return true
} else {
return false
}
}

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

isOdd(n: 5)

BelowSolutionWorksWellButStillDontKnowWhatThisSymbol%Indicates
func isOdd(n: Int) -> Bool {

if n % 2 != 0 {
    return true
} else {
    return false
}

}
isOdd(n: 5)
isOdd(n: 7)

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

% operator is my fave!

And how do you call this function

BelowSolutionWorksWellButStillDontKnowWhatThisSymbol%Indicates
func isOdd(n: Int) -> Bool {

if n % 2 != 0 {
    return true
} else {
    return false
}

}
isOdd(n: 5)
isOdd(n: 7)

How do you call this function ?
When I type "isOdd(n: 5)" I got "Expressions are not allowed at top level"

func isOdd(n:Int) ->Bool {
if n%2 == 0{
return true
}
else{
return false
}
}
let testno = Int(readLine()!)!
var res = isOdd(n:testno)
print(res)

This is my solution

func isOdd(n: Int) -> Bool {

    if n % 2 != 0 {
        return true
    } else {
        return false
    }
}

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)
