Write a static recursive method in Java called mrecursiv that displays all of the permutations of the charactersin a string passed to the method as its argument. For example, the character sequence abc has thefollowing permutations: acb, bac, bca, cab, cba. Then Write a static method called getInput that get aninput string from the user and passed it to the mrecursiv method written above in a method call.
Write a recursive method in java that returns a string that contains the octal representation of a positive integer. Test your method.
Hint: An octal number is the base-8 number system, and uses the digits 0 to 7. For example, the number 12 can be converted to octal number as follows:
Divide by 8, the remainder represents the first digit so 12/8 = 1 and the remainder is 4 so the first digit is 4. The quotient is 1. Then we divide 1 over 8 we get zero and the remainder is 1. The second digit is 1 and we stop.
The equivalent octal number for 12 is 14.
Write a recursive Java method that takes a String as a parameter and returns true if the String is a palindrome. You may assume that the string only contains lower case characters (i.e. no numbers, spaces, punctuation, etc).

- Write a recursive method in java public static long numPaths(int r, int c) which can solve the following scenario: a checker is placed on a checkerboard. What are the fewest moves to get to the upper left corner(0,0)? You can only move sideways or vertically. No diagonal moves. Once you have that calculation, how many different ways are there to get to the upper left corner? this is my code but I am getting stock overflow, I'm not reaching my base case. public static long numPaths(int r, int c) { //base case if (r==0 && c==0 || r==0 || c==0) return 1; else { return numPaths(r, c--) + numPaths(r--, c); } }arrow_forwardWrite a Java program that asks the user to enter a string and counts how many times the letter "s" or "S" appears in the string. Display that number and then display the string that many times. Requirements: Call a method that gets the string from the user. Use recursion to ensure the string has at least 5 characters. Call a method that returns the number of times the letter "s" or "S" appears in the string. This method should use recursion. Call a method that takes the number of times the letter"s" or "S" appeared in the string and display the original string that was obtained from the user that many times using recursion. Call a method that sorts the letters in the string and searches for the letter "m".
