Problem Statement

This task is about arrays. For hashes or associative arrays, please see Creating an Associative Array. For a definition and in-depth discussion of what an array is, see Array.

Show basic array syntax in your language. Basically, create an array, assign a value to it, and retrieve an element   (if available, show both fixed-length arrays and dynamic arrays, pushing a value into it). Please discuss at Village Pump:   Arrays.
Please merge code in from these obsolete tasks:

Let's start with the solution:

a = [1,2] -- or: a = list(1,2)
put a[2] -- or: put a.getAt(2)
-- 2
a.append(3)
put a
-- [1, 2, 3]
a.deleteAt(2)
put a
-- [1, 3]
a[1] = 5 -- or: a.setAt(1, 5)
put a
-- [5, 3]
a.sort()
put a
-- [3, 5]

ba = bytearray(2, 255) -- initialized with size 2 and filled with 0xff
put ba
-- 
ba[1] = 1
ba[2] = 2
ba[ba.length+1] = 3 -- dynamically increases size
put ba
-- 
ba[1] = 5
put ba
--
