Look at the following method. public static int test2(int x, int y) { if ( x < y) { return -5; } else { return (test2(x - y, y + 5) + 6); } } What is returned for test2(10, 20)? Question 6 options: a 1 b 10 c 6 d -5
Consider the following method: Linel: public static int mystery(int n) { Line2: if (n < 10) { ine3: return n; Line4: } else { Line5: int a = n/10; Line 6: int b = n % 10; Line 7: return mystery(a + b); Line 8: } Line 9: } What is the result of the following call? System.out.println(mystery(648)); 18 8 12
24) (3x2 marks) Consider the following method: public static int mysteryl (int a, int b) ( int result 0: if (a <b) ( else if (a b) else ( return result: result mystery2 (a) mystery2 (a)i result - mystery2 (b) result-ab; public static int mystery2 (int x) f int countx for (int i 0; іск; i++) count +1: return counti What are the values stored in the variable result after the following method calls? a) int result mysteryl(4,1): b) int...
Recursive Tracing. For each call to the following method, indicate what value is returned: public static int mystery(int n) { if (n < 0) { return -mystery(-n); } else if (n == 0) { return 0; } else { return mystery(n / 10) * 10 + 9 - (n % 10); } Call Value Returned mystery(0) mystery(5) mystery(13) mystery(297) mystery(-3456) } Can any one help me with it?
b) Consider the following code. public static int f(int n) if (n == 1) return 0; else if (n % 2 == 0). return g(n/2); else return g(n+1); public static int g(int n) int r = n % 3; if (r == 0) return f(n/3); else if (r == 1) return f(n+2); else return f(2 * n); // (HERE) public static void main(String[] args) { int x = 3; System.out.println(f(x)); (1) (5 points) Draw the call stack as it would...
Consider the following methods’ headers: public static int one(int a, char b, double c, String d) public static double two(double x, double y) public static char three(int r, int s, char t, double u) Answer the following questions: Q1) What is the signature of method one? Answer: Q2) What is the return type of method two? Answer: Q3) What the formal parameters of method three? Answer: Q4) How many actual parameters are needed to call the method three? Answer: Q5)...
Problem 5) Simplify the code for the following method as much as you can.(Java) public static int inTheInterval(int n) { if (n < 0) return -1; else if (0 <= n && n <= 1) return 0; else if (n > 1) return 1; return 42; // we never get here }
In the following program: public class Problem2{ public static int sample(int x, int y){ int z; ...... } public static void main(String[] args) { int a, b; ...... sample(a,b); } } (1) What is the return type of sample? (2) What are the local variables of sample? (3) What are the parameters of sample? (4) What are the arguments of sample? (5) Is sample a per-object method? Or a per-class method? (6) Is sample a public method, or private method?
3. Consider the mystery method given. public static int mystery ( int n) [ if (n == 0 ) { return 1; How do we get the values for recurse? else if (n%2 == 0 ) { int recurse = mystery ( n - 1); int result = recurse + n; return result; since n =5, we go to the else statement and do int recurse = mystery(5-1) which equals 4? why is 3 written? else { int recurse =...
