1. Create an object named "pair" that contains the value of the element and its primary index position. 2. Get all the pair in a list, sort that list with customized comparator. 3. Traverse through the pair list, using the graph theory to identify circles consisting the group of element need to be swapped. 4. Specify the number of swaps.
As we go we will need to perform the swaps, becasue we are not guranteed 1 swap will fix both elements. We will do this on both a ascending sort and a descending sort as both meet the minimal requirement Time Complexity: O (n log (n)) //We must sort the input Space Complexity: O (n) //We store the input in an array */ import java.io.*; import ...
Sep 21, 2018 · Short Problem Definition: Whenever George asks Lily to hang out, she’s busy doing homework. George wants to help her finish it faster, but he’s in over his head! Can you help George understand Lily’s homework so she can hang out with him? Consider an array of m distinct integers, arr = [a [0], a [1], …, a [n-1]].
Lily's Homework. See the original problem on HackerRank. Solutions. The sum is minimal when the array is sorted. Both descending and ascending order will yield the minimum sum of the absolute difference of adjacent elements. We need to count the number of swaps in both cases. To find the number of swaps we have to find the number of cycles in the array. For instance, given the following array: 1

Aug 1, 2023 · I am looking at the HackerRank problem Lily's Homework: Consider an array of distinct integers, arr = [a[0],a[1],...,a[n-1]]. [You] can swap any two elements of the array any number of times. ... The solution consists of sorting the array, while remembering for each value its index in the original input array. There are two candidates that minimize the sum of differences: either sorting the input in ascending order, or in descending order. ...

Prep stage: create map with: keys : values from input list, values : indexes of values from input list, make a copy of sorted input list. Algo stage: Iterate through input list, and compare current value (lets call it cv) against value from sorted list (lets call it scv). If it is diffrent: increment number of swaps.
