“print()” function: • “print()” function is used to display the output on the screen. • It is the built-in function that displays the output of the program . • The arguments are surrounded within “()” parentheses. • The “print()” function is called by the word “print” with the set of parentheses. Algorithm : Algorithm to display the result of the given program is as follows: • The value “5” is assigned to the variable “a”. • The value “2” is assigned to the variable “b”. • The value “3” is assigned to the variable “c”. • Calculations are performed using math expression, and then the value is stored in the variable “result”. • Displaying the output using “print()” function.

Question

7. See the code below and solve the following. public class Test { public static void main(String[] args) { int result = 0; } result = fn(2,3); System.out.println("The result is: + result); // fn(x, 1) = x // fn(x, y) = fn(x, y-1) + 2, when y>1 public static int fn(int x, int y) { if (x <= 1) return x; else return fn(x, y-1) + 2; } } 7-1. This program has a bug that leads to infinite recursion. Modify fn(int x, int y) method to fix the problem. (2 point) 7-2. Manually trace the recursive call, fn(2,3) and show the output (step by step). (2 point) 7-3. Can you identify the Base Case in recursive method fn(int x, int y)? (1 point)

Program Plan Intro

“print()” function:

• “print()” function is used to display the output on the screen.

• It is the built-in function that displays the output of the program.

• The arguments are surrounded within “()” parentheses.

Write a program that reads a list of integers from input and determines if the list is a palindrome (values are identical from first to last and last to first). The input begins with an integer indicating the length of the list that follows. Assume the list will contain a maximum of 20 integers. Output "yes" if the list is a palindrome and "no" otherwise. The output ends with a newline. Hints: - use a for loop to populate the array based on the specified size (the first number entered) - use a for loop to check first value with last value, second value with second from end, etc. - if the values do not match, set a Boolean variable to flag which statement to output (yes or no) Ex: If the input is (remember to include spaces between the numbers): 6 1 5 9 9 5 1 the output is: yes Ex: If the input is: 5 1 2 3 4 5 the output is: C++ coding
