Hello what's the correct answer??

Please I need to know why my code is not right?

arrays.swift 
var arrayOfInts = [1, 2, 3, 4, 5, 6]

arrayOfInts.append(7)

arrayOfInts += [8]

arrayOfInts.count

arrayOfInts = [1, 2, 3, 4, 5, 6, 7, 8]

let value = arrayOfInts[4]

arrayOfInts.removeAtIndex(5)

let discardedValue = arrayOfInts

Hey there,

you almost got it right and you already used the removeAtIndex method on the arrayOfInts array correctly and you created the discardedValue constant. Now just combine those two things and save the value you remove from the array into the discardedValue constant.

Like so:

// Enter your code below
var arrayOfInts = [1, 2, 3, 4, 5, 6]
arrayOfInts.append(7)
arrayOfInts += [8]
let value = arrayOfInts[4]
let discardedValue = arrayOfInts.removeAtIndex(5)

I hope that helps, good luck! :)
