public static int countCharacter(String str, char c) { // This recursive method takes a String and a char as parameters and // returns the number of times the char appears in the String. You may // use the function charAt(int i) described below to test if a single // character of the input String matches the input char. // For example, countCharacter(“bobbie”, ‘b’) would return back 3, while // countCharacter(“xyzzy”, ‘y’) would return back 2. // Must be a RECURSIVE...

Write two recursive methods that validate if the given string follows allowed patterns: isIdentifier method checks if the given string is a valid java identifier: must start with a letter, the subsequent characters must be letters or digits the length of a valid identifier must be at least one isDashDotCode method checks if the given string is a valid word in the following pattern: the characters must be dots or dashes the minimum length of a valid word is one...
Please write and draw the recursive trace, and please explain,
thank you!
Problem 1. [26 pts] Given the Fibonacci numbers, defined as: Fo 0, F1-1, F k Fk2 write or draw the recursive trace of the calculation of the 5th Fibonacci number (Fs 5) with the following Algorithm (which is based on linear recursion) Algorithm Fibonacci Linear (k) Input: a positive integer value k Output: a pair of Fibonacci numbers (F., F..) if k < 2 then R-1 return (R,...

Write a recursive function that takes a string as an input and returns the reverse of the string. 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 produce the following output: * c bc abc
Provide the mathematical expression (in infix form) represented by the following postfix string and trace through the stack based algorithm step by step in the evaluation of the above postfix string. 7 16 5 + 2 * 4 3 + / +
Find the following: (a) trace(J). b) trace nm (c) trace (I)
Java Program Write a recursive method that takes a string and return a string where every character appears twice. Output must match exactly as below: only two LL's since there is already two of the character For example, if the string is “HELLO”, it will return “HHEELLOO”. Write a program to test it. must be recursive!!!
Write a recursive function, take a String as input, return true, if the String is a palindrome; false otherwise. For instance, if the input is: “A nut for a jar of tuna” Then the return value is true. Notice that the non English letters are ignored; the spaces are ignored; and it is NOT case sensitive. You must write recursive function. You shall turn in a complete program, including main function to use your function to test if a String...
