• Create a * based Christmas tree that looks like the following:
  • *
  • ***
  • *****
  • *******
  • **********
  • *
• Use a loop to algoritmically create the top five lines of the tree
  • The first line has 4 spaces followed by 1 *
  • The next line has 3 spaces followed by 3 *
  • The next line has 2 spaces followed by 5 *
  • The next line has 1 spaces followed by 7 *
  • The last line has 0 spaces followed by 9 *
• Store each output line on the tree in an Array
• Finally use one more array to output the contents of your Array

My code is as follows:

var arr = [String]()

for i in 1...5 {

for _ in 1...2*i-1 {

arr.append("*")

}

arr.append(" ")

}

for i in arr{

print(i, terminator: "")

}

it outputs the image above. I need to make the output look like a tree. How do I fix this?
