Kata

You are given a string of lowercase letters and spaces that you need to type out. You may notice some square brackets inside the string.

• If it contains letters, type out the text inside then copy it.
• If it is empty, paste the copied text
• If it contains a number, paste the copied text that number of times.

Here are a few examples.

[ten ]ten [3] -> ten ten ten ten ten

[one hundred and ]one, []two, []three -> one hundred and one, one hundred and two, one hundred and three

[100][repeat me][2] -> repeat merepeat merepeat me (pasting nothing 100 times is still nothing)

Notes:

• Although it is possible, nested loops will not be tested.
• The number inside the bracket will always be a positive integer (1, 2, 3...).
• All inputs will be valid (no unclosed brackets, etc)

More examples in the smaple tests.

Good luck!
