Please do not change any of the method signatures in either class. Implement the methods described below. Partition.java public static int partitionLomuto(int[] arr, int low, int high) Implement this method using Lomuto’s partition algorithm. This is the algorithm that we discussed in class that chooses the last element as the partition and iterates through the array swapping an element that belongs in the low side with the lowest (farthest left) element on the high side. At the end, the pivot is swapped with the lowest element (farthest left) element on the high side. This method should return the index of the pivot element, which is now in its correct position in the array. See the pseudocode below. partition(arr, p, r) x = arr[r] i = p – 1 for j = p to r – 1 if arr[j] ≤ x i = i + 1 swap arr[i] and arr[j] swap arr[i+1] and arr[r] return i+1 What sort of input arrays will enable Hoare’s algorithm to still create relatively equal size partitions whereas Lumoto’s algorithm will create unequal partitions? Write your answer in the location specified in Partition.java. Below is Method signature class: package sorting; import java.util.Arrays; public class Partition { public static int partitionLomuto(int[] arr,int low, int high) { return 0; } /***********ANSWER QUESTION HERE*****************/ /* * What sort of input arrays will enable Hoare’s algorithm to still create relatively * equal size partitions whereas Lomuto’s algorithm will create unequal partitions? */ }

Partition.java
public static int partitionLomuto(int[] arr, int low, int high)
Implement this method using Lomuto’s partition
partition(arr, p, r)
x = arr[r]
i = p – 1
for j = p to r – 1
if arr[j] ≤ x
i = i + 1
swap arr[i] and arr[j]
swap arr[i+1] and arr[r]
return i+1
What sort of input arrays will enable Hoare’s algorithm to still create relatively equal size partitions whereas Lumoto’s algorithm will create unequal partitions? Write your answer in the location specified in Partition.java.
Below is Method signature class:
package sorting;
import java.util.Arrays;
public class Partition {
public static int partitionLomuto(int[] arr,int low, int high) {
return 0;
}
