Do not use static variables to implement recursive methods.
USING JAVA
USING:
// P4
public static int min(int [] a, int begin, int end) {
}
Implement a recursive method min that accepts an array and returns the minimum element in the array. The recursive step should divide the array into two halves and find the minimum in each half.
Demonstrate the output of min on the array int [] a = { 2, 3, 5, 7, 11, 13, 17, 19, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 23, 29, 31, 37, 41, 43 }
Problem 1
A. Consider the following recursive method.
def foo1(n):
if n == 2:
return 1
else:
return 3 * foo1(n – 1)
What value is returned as a result of the call foo1(5)? Show the recursive calls generated.
B. Consider the following recursive method.
def foo2(n):
if n > 0:
print(n, end=’ ‘)
foo2(n-1)
What is the output of the call foo2(5)
Problem 2
Make sure your code is readable and well-documented. Each function must also begin with a title block that describes the task of the function, input parameters and return value.
Write a recursive function that takes a string as an input and returns the reverse of the string.
2. Write a recursive function rec_string that produces the output shown below for the corresponding function calls. Write a main function to test the function.
Method call rec_string(‘abcde’), will produce the following output:
*
e
de
cde
bcde
abcde
Method call rec_string(‘abc’), will…
Trace and document every step of execution of the following program:
public class Trace {
public static void main(String[] args) { int[] num = {1, 3, 6, 9, 12 };
for (int i = 4; i >= 0; i--) { num[i] +=1; } num[0] *=num[4]; } }
