Question
The following recursive method called z is created. This method accepts two parameters: A string s, and an integer index
The code in the method is:
if (index == s.length())
return ""; <------ base case
if(index % 2 == 0)
return ""+ s.charAt(index) + z(s,index+1); <---- recursive call
else
return z(s,index+1); <----- recursive call
What would be the output with the call: z("javajavajava",0);

- solve q7 only pleasearrow_forwardThe following recursive method get Number Equal searches the array x of 'n integers for occurrences of the integer val. It returns the number of integers in x that are equal to val. For example, if x contains the 9 integers 1, 2, 4, 4, 5, 6, 7, 8, and 9, then getNumberEqual(x, 9, 4) returns the value 2 because 4 occurs twice in x. public static int getNumberEqual(int x[], int n, int val) { if (n< 0) ( return 0; } else { if (x[n-1) == val) { return getNumberEqual(x, n-1, val) +1; } else { return getNumber Equal(x, n-1, val); } // end if ) // end if } // end get Number Equal Demonstrate that this method is recursive by listing the criteria of a recursive solution and stating how the method meets each criterion.arrow_forward1 public static int sum(int x, int y){ 2 int z = x +y; 3 return z; 4 } 5 public static void main(String[] args){ 6 … 7 sum(a+2, b); 8 … 9 } write the signature of the method sum: sum(int,int) *Method name/parameter list list local variables of sum: x, y, and y are local variables of the function. list the parameters of sum: int x, int y write the line number where a call to sum occurs 7 list the arguments for the above call list the return type of sum here ______________arrow_forward

In the main method of your program accept the value of n from the user as a command-line argument and then call your function named Fibonacci with this value.
