' Task 1: Missing Numbers
' Submitted by: Mohammad S Anwar
'
' You are given an array of unique numbers.
'
' Write a script to find out all missing numbers in the range 0..$n where $n
' is the array size.
'
' Example 1
'
' Input: @array = (0,1,3)
' Output: 2
'
' The array size i.e. total element count is 3, so the range is 0..3.
' The missing number is 2 in the given array.
'
' Example 2
'
' Input: @array = (0,1)
' Output: 2
'
' The array size is 2, therefore the range is 0..2.
' The missing number is 2.
