 # **HELP** with Arrays

So I have a array of 6 numbers and I need to append an asterisk to set of three number that's generated in the loop. But only the second set numbers. It loops to 25 then starts back at 1.

For example: [1, 2, 3, 4, 5, 6] [4*, 5*, 6*, 7, 8, 9] [7*, 8*, 9*, 10, 11, 12] [10*, 11*, 12*, 13, 14, 15] [...]

Here is my code for generating the loop but I don't know how to append the asterisk.

let original = [1, 2, 3, 4, 5, 6]
var currentArray = original
print("currentArray =", currentArray)
var stop = false
repeat {
currentArray = currentArray.map() { (\$0 + 2) % 25 + 1}
print("currentArray =", currentArray)
stop = currentArray == 25
} while !stop

The formatted op's code

``````let original = [1, 2, 3, 4, 5, 6]
var currentArray = original
print("currentArray =", currentArray)
var stop = false
repeat {
currentArray = currentArray.map() { (\$0 + 2) % 25 + 1 }
print("currentArray =", currentArray)
stop = currentArray == 25
} while !stop
``````

You can not append the asterisk, because `currentArray` is an array of `Int`, and `4*` is not a valid `Int`.

If all you care is the printed output, you can expand the printing logic, or create a new array of `String`, and append asterisk manually.

Yes, I need it appended to the output. Just what's printed out.

The easiest way is probably to have custom logic for printing.

Printing array of `String` will give you `["1*", "2*", "3*", "4", "5", "6"]`. You probably don't want the double quote.

You could try to come up with the logic yourself first since there are many ways to do it, and might be the point of the exercise.

In any case, this is one way you can do:

``````var current = [1, 2, 3, 4, 5, 6]

while current != 3 {
print("currentArray = [\(current.first!)*", terminator: "")
var starCount = 2
for value in current.dropFirst() {
if starCount > 0 {
// There's some stars left. Print it out.
print(", \(value)*", terminator: "")
starCount -= 1
} else {
print(", \(value)", terminator: "")
}
}
print("]")

current = current.map() { (\$0 + 2) % 25 + 1 }
}
``````

Awesome!!!
Thats it!
Thank you MUCH!!!
