Relative Sort Array Lab

42.1% Acceptance

In this lab, you will be given two arrays arr1 and arr2, where the elements of arr2 are distinct, and all elements in arr2 are also in arr1. Your task is to sort the elements of arr1 such that the relative ordering of items in arr1 are the same as in arr2. Elements that do not appear in arr2 should be placed at the end of arr1 in ascending order.

This lab will focus on testing your ability to implement an algorithm that is able to correctly process and manipulate the given arrays following the challenge rules. You will write a function relativeSortArray that takes two parameters:

  • arr1: an array of integers
  • arr2: an array of integers

The function should return the sorted array arr1 following the challenge rules described above.

Examples

Example 1:

Input: arr1 = [2,3,1,3,2,4,6,7,9,2,19], arr2 = [2,1,4,3,9,6] Output: [2,2,2,1,4,3,3,9,6,7,19]

Example 2:

Input: arr1 = [28,6,22,8,44,17], arr2 = [22,28,8,6] Output: [22,28,8,6,17,44]

Constraints:

  • 1 <= arr1.length, arr2.length <= 1000
  • 0 <= arr1[i], arr2[i] <= 1000
  • All the elements of arr2 are distinct.
  • Each arr2[i] is in arr1.

Now, you will have to create Challenges for this lab and Evaluation script for each of those challenges. Follow the guidelines discussed in the initial conversation and make sure to use ESM import/export everywhere. Keep the written copies for everything as mentioned in the guidelines and always write bug-free code with proper instructions provided for the fellow students.
