Problem Statement

Sort an array (or list) of integers in ascending numerical order.

Use a sorting facility provided by the language/library if possible.

Let's start with the solution:

import algorithm
  
var a: array[0..8, int] = [2, 3, 5, 8, 4, 1, 6, 9, 7]
a.sort(Ascending)
for x in a:
  echo x
