old_contents: sortTransformedArray.js
  
new_contents: Given a sorted array of integers nums and integer values a, b and c.
  Apply a function of the form f(x) = ax2 + bx + c to each element x in the array.
  
  The returned array must be in sorted order.
  
  Expected time complexity: O(n)
  
  Example:
  nums = [-4, -2, 2, 4], a = 1, b = 3, c = 5,
  
  Result: [3, 9, 15, 33]
  
  nums = [-4, -2, 2, 4], a = -1, b = 3, c = 5
  
  Result: [-23, -5, 1, 7]
