Assume that a 5 element array of type string named boroughs has been declared and initialized. Write the code necessary to switc

h (exchange) the values of the first and last elements of the array. So, for example, if the array's initial values were: brooklyn queens staten_island manhattan bronx then after your code executed, the array would contain: bronx queens staten_island manhattan brooklyn

Answer:

Explanation:

Let's do this in python. First we can set a placeholder variable to hold the first element of the array, then we can set that first element to the last element (5th) of that array. Then we set the last element of that array to the placeholder, which has value of the original first element of the array

placeholder = boroughs[0] # in python, 0 is the first element or arra

boroughs[0] = boroughs[-1] # -1 means the last element of the array

boroughs[-1] = placeholder

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.");

  }

}
