Sort Transformed Array(LeetCode 360):

Problem

Given a sorted integer array nums and three integers a, b and c, apply a quadratic function of the form f(x) = ax2 + bx + c to each element nums[i] in the array, and return the array in a sorted order.

 

Example 1:

Input: nums = [-4,-2,2,4], a = 1, b = 3, c = 5
Output: [3,9,15,33]

Example 2:

Input: nums = [-4,-2,2,4], a = -1, b = 3, c = 5
Output: [-23,-5,1,7]

 

Constraints:

  • 1 <= nums.length <= 200
  • -100 <= nums[i], a, b, c <= 100
  • nums is sorted in ascending order.
