- Java- Consider this method declaration: void quiz(int i) { if (i > 1) { quiz(i/2); quiz(i/2); } system.out.print(“*”); } How many asterisks are printed by the method call quiz(4) ?Do not use static variables to implement recursive methods. USING JAVA USING: // P5 public static long computePay(int day) { } You have been offered a job that pays as follows: On the first day, you are paid 1 cent, on the second day, 2 cents, on the third day, 4 cents and so on. In other words, your pay doubles every day. Write a recursive method computePay that for a given day number computes the pay in cents. Assume that you accumulate all the money that you are paid. Write a recursive method computeSavings that computes the sum that you have accumulated on a given day. Show the output of computePay and computeSavings for day number 39.Note: Java Consider the following recursive method: public static int Fun(int x) { if(x == 0) //line 1 return 0 //line 2 else if( x == 1) //line 3 return 1; //line 4 else //line 5 return (x*Fun(x-1)); //line 5 } a) Is Fun(4) a valid call? If so, what is the value? If not, explain why? Answer: b) Is Fun(-4) is a valid call? If so, what is the value? If not, explain why? Answer: (c) Consider the following method. public static int res(int[] list, int first, int last) { if (first == last) return list[first]; else return list[first] + res(list, first + 1, last); } Given the declaration int[] A = {2, 4, 6, 8, 10}; What is the output of the following statement? out.println(res(A, 0, 2)); out.println(res(A, 0,…

How to use it in java? public static double calculateBMI(double height, double weight) {return 703 * weight / (height * height);}
- Study the method in Java below and answer the questions that follow. public static int linearSum(int[] data, int n) { if (n == 0) return 0; else return linearSum(data, n-1) + data[n-1]; } a) What does the method perform? b) Name and explain the type of recursion implemented by the method. c) Analyse the running time of the algorithm represented by the method.There are a few errors in this java code: can you fix it please, its basically a debugging exercise: public static int sum(int n){ int n; for (int i=1; i<=n;i--){ sum++; } return sum; } }Show the derivation of the asymptotic run time, O(n), for each of the following methods. You may use the text highlighting technique shown in class, or list the individual Java statements along with the number of times each is executed as a function of the input size, n. public static void checkerboard(int n){ for (int row = 0; row < n; row++) { for (int col = 0; col < n; col++){ if ((row+col)%2 == 0) { // Print a single hashtag System.out.print("#"); } else { // Print a single space System.out.print(" "); } } // Complete the line System.out.println(); } }

Of course, this would result in a capital gain (or loss) when the shares are sold. This is computed as the difference between the shares' selling price and the price was originally paid to buy it. When an investor has a single share of stock, the process is easy. However, when (s)he sells multiple shares of stocks, bought over a period of time and possibly with different prices, the first step is to identify which shares of stocks are to be sold. There are two accounting principles (protocols) that are followed depends on the market of stocks: the shares bought last to be sold first, and the other is to sell the shares that stayed the longest. You are required to implement a program to calculate the possible capital gain/loss using these two protocols. This would facilitate the process for investors to know which market to go for and invest their…Can you please give an example of a Java code using the recursion method to call a method named "sum" which will multiply numbers from 1 to the input number: Example, the sum method should take a number say 20 and output product of: 20*19*18*17*.....*1.
