- write a recursive version. The function takes two string parameters, s1 and s2 and returns the starting index of s2 inside the first string s1, or -1 if s2 is not found in s1. You must not use any loops; you also cannot use the string member functions find or rfind. You may use the member functions size, at and substr. Your function must be recursive.Recursion Practice Welcome back! In this lab, we will be reviewing recursion by practicing with some basic recursion problems. Objectives Increase familiarity with recursive logic by working through several recursive problems. Taking into consideration a few corner cases through analyzing the test cases. Using a regex expression that will remove punctuation. Getting Started This lab includes the following .java file: L4/└── Recursion.java└── Main.java**Main.java is a read-only file used for testing. It is not included in the starter jar.Here is the starter jar if you would like to code in a different environment: L4.jar. Please complete ALL functions. Make sure to read the description for each function carefully. Do not include any for or while loops in your methods. These can all be completed in a purely recursive style, so do it recursively! In the spirit of incremental development, implement each method one at a time, look at the test cases and take into consideration what is…3. Largest: a recursive function that computes the largest value for an integer array of positiveand negative values. For example, for the array below, the function largest should return 22,which is the largest value in the array. You can assume there are no more 20 integers in thearray. Think of how to formulate the recurrence relation in this problem yourself.

Given two strings, this function returns true if the two strings are identical, but are in reverse order. Otherwise it returns false. For example, if the inputs are "tac" and "cat", then the function should return true. Examples: isReverse("tac", "cat") -> true Your Answer: 1 public boolean isReverse(String s1, String s2) { 2. if > 3. 4. else if > return true; return false; 5. 6. else { String s1first = String s2last return s1first.equals (s2last) && 51. substring(0, 1); s2, substring(s2.length() 1); 7. 8. 6. isReverse(s1.substring(1), s2.substring(0, s2.length() 1)); { 12} 1:11AM 50°F Clear 12/4/2021Consider the following function: void fun_with_recursion(int x) { printf("%i\n", x); fun_with_recursion(x + 1); } What will happen when this function is called by passing it the value 0?
- Write a recursive function that accepts a number and returns its factorial. b. Write a recursive function that accepts an array, its size and the index of the initial element as arguments. The function fills the array with the elements of the following sequence: n1 = 3, nk+1 = nk+35 c. Write an iterative and a recursive versions of the binary search. In C++ codingRecursive Parsing Calculator HINT: Before attempting this exercise, see the simplerecursiveparser.java in the example programs of the recursion unit on QM+ and the related booklet about Language, grammars and recursion that explains it. Write a program that recursively parses expressions, input as strings, from the following recursively defined language and calculates and prints out the answer to the calculations. Legal expressions in this language involve putting the operator before its arguments (this is called Polish notation). = * | T = 0|1|2|3|4|5|6|7|8|9|A|B|C Instead of writing 3*2, in this language you write *32 (which evaluates to 6). EXP stands for expressions. means multiply the two digits that follow (after evaluation) so *24 is 8 and *5*34 is 60 as it first multiples 3 and 4 to get answer 12 then multiplies 5 and 12 to get 60. Tn means add the next 3 numbers from n (so eg T3 means 3+4+5=12, T7 means 7+8+9-24), DIGIT gives a way to express numbers up to 12 as a sıngle…1. Write a recursive function that takes as a parameter a nonnegative integer and generates the following pattern of stars. If the nonnegative integer is 4, then the pattern generated is:********************Also, write a program that prompts the user to enter the number of lines in the pattern and uses the recursive function to generate the pattern. For example, specifying 4 as the number of lines generates the above pattern. 2. A palindrome is a string that reads the same both forward and backward. For example, the string "madam" is a palindrome. Write a program that uses a recursive function to check whether a string is a palindrome. Your program must contain a value-returning recursive function that returns true if the string is a palindrome and false otherwise. Do not use any global variables; use the appropriate parameter.
- Write a recursive function to generate the following pattern of stars:** ** * ** * * ** * ** **Also, write a program that prompts the user to enter the number of lines in the pattern and uses the recursive function to generate the pattern. For example, specifying 4 as the number of lines generates the above pattern.Problem 1: Recursion to Generator You worked with these last homework. For this homework, you'll write the tail recursion, while, and generator. This is a reminder that in the starter code, we are providing you with the regular recursion code, and the functions you must implement must utilize tail recursion, a while loop, or a generator as specified. In your starter code, function names will end in _t, _w, or _g if the function needs to be implemented using tail recursion, a while loop, or a generator, respectively. Review the lecture slides to learn more about generators. p(0) p(n) = 10000 = p(n-1) + 0.02p(n − 1) c(1) = 9 c(n) = 9c(n-1) + 10-1 — c(n − 1) d(0) = 1 d(n) = 3d(n-1) + 1 Programming Problem 1: Recursion to Generators • For reach function you'll write the tail recursive form, while, and generator. • We have added the signature to help you-in particular, c(n) requres two accumula- tors. (1) (2) (3) (4) (5) (6) (7)Create a recursive function that simulates the range function. For example: Enter the range (begin, end, increment) separated by spaces: 3 15 3 [3,6,9,12]
