The ArrayList class contains a trim method that resizes the internal array to exactly the capacity. The trim method is intended

andreev551 [17]

Answer:

public void trimToSize() {

modCount++;

if (size < elementData.length) {

elementData = (size == 0)

? EMPTY_ELEMENTDATA

: Arrays.copyOf(elementData, size);

}

Now, the running time for copyOf() function is O(N) where N is the size/capacity of the ArrayList. Hence, the time complexity of trimToSize() function is O(N).

Hence, the running time of building an N-item ArrayList is O(N^2).

Please find the sample code below.

CODE

==================

import java.util.ArrayList;

public class Driver {

public static void main(String[] args) throws Exception{

int N = 100000;

ArrayList<Integer> arr = new ArrayList<>(N);

long startTime = System.currentTimeMillis();

for(int i=0; i<N; i++) {

arr.add(i);

arr.trimToSize();

}

long endTime = System.currentTimeMillis();

double time = (endTime - startTime)/1000;

System.out.println("Total time taken = " + time + " seconds.");

}

Homework: Insertion Sort

Serga [27]

Answer:

Explanation:

I have written the code in Java. It contains the class Insertion Sorter which has the InsertionSort function. This function uses the insertion sort algorithm to sort a comparable array and if it fails to do so for whatever reason it throws an Illegal ArgumentException. If it sorts the array correctly it returns the number of changes that needed to be made in order to correctly sort the array. Due to technical difficulties I have attached the code as a text document below and proof of output in the picture below as well.
