  Problem name: Sort the People

  Difficulty level: Easy

  Problem description: 

    You are given an array of strings names, and an array heights that consists of distinct positive integers. Both arrays are of length n.

    For each index i, names[i] and heights[i] denote the name and height of the ith person.

    Return names sorted in descending order by the people's heights.

  Examples: {

    Example 1: {
      Input: names = ["Mary","John","Emma"], heights = [180,165,170]
      Output: ["Mary","Emma","John"]
      Explanation: Mary is the tallest, followed by Emma and John.
    }

    Example 2: {
      Input: names = ["Alice","Bob","Bob"], heights = [155,185,150]
      Output: ["Bob","Alice","Bob"]
      Explanation: The first Bob is the tallest, followed by Alice and the second Bob.
    }
  }
