- Q1 java : If in the ArrayStack, the first element that we push to the stack, is stored in location capacity – 1 (capacity is the capacity of the array theData) in the array theData and the subsequent elements that we push, we keep on adding before the last element added in the array. That is, in the constructor of class ArrayStack, we initialize the topOfStack to capacity and we write the push method as follows: public E push(E obj) { if (topOfStack == 0) reallocate(); topOfStack--; theData[topOfStack] = obj; return obj; } This push method can work but the if statement should be: if (topOfStack == theData.length - 1) reallocate(); This push method will work provided we modify the reallocate method. This push method can work, but topOfStack-- ; should come after theData[topOfStack] = obj; This push method can work, but topOfStack-- ; should be topOfStack++;Write a test client TestBinarySearch.java for use in testing the implementations of min(), max(), floor(), ceiling(), select(), rank(),deleteMin(), deleteMax(), and keys() that are given in the text.

Implement a version that outputs images with full dynamic range (0–255 pixel intensity). In other words, for each color channel (r, g, b), rescale the range of pixel values for that channel to include both 0 and 255. After normalizing, there should be at least one pixel with a red value of 0, at least one pixel with a red value of 255, at least one pixel with a green value of 0, etc. To normalize a list of numbers nums to the range 0–n, set nums[i] = (nums[i]−min(nums))/(max(nums)−min(nums))∗n for all i. Be careful! When max(nums) == min(nums), you should not touch that list (why?).Can you add class level comments, function level comments and inline comments In this line int i,n=0,s=0; they say the assigned value is not used can you fix that package avgsum;import java.util.Scanner; /**** @author Zaahid*/public class AvgSum { /*** @param args the command line arguments*/public static void main(String[] args) { int i,n=0,s=0;double average;{System.out.println("Enter the 5 numbers : "); }for (i=0;i<5;i++){Scanner in = new Scanner(System.in);n = in.nextInt();s +=n;}average=s/5;System.out.println("The sum of 5 numbers is : " +s+"\nThe Average is : " +average);}
