[Solved] Table of integers right aligned

Question

You are simply printing the array and the description method of Array will show the list of values separated by commas with the brackets.

If you want any other output you need to generate it yourself.

Replace your current print with the following:

let line = table.map { String(format: "%4d", $0)}.joined()
print(line)

This maps the array of Int into an array of String and then joins those strings into a single string with no separator between them. Each Int is formatted into a String that will take four spaces and the number will be right-aligned within those four spaces. Adjust as needed.
