Use back substitution method to compute the following recursive function. Note that final results must be presented as a function of n. Show at least three substitutions before moving to k steps to get credit.

Write a recursive method that returns the value of N! (N factorial) using the definition given in this chapter. Explain why you would not normally use recursion to solve this problem.

Make a code using Recursion The countSubstring function will take two strings as parameters and will return an integer that is the count of how many times the substring (the second parameter) appears in the first string without overlapping with itself. This method will be case insensitive. For example: countSubstring("catwoman loves cats", "cat") would return 2 countSubstring("aaa nice", "aa") would return 1 because "aa" only appears once without overlapping itself. public static int countSubstring(String s, String x) { if (s.length() == 0 || x.length() == 0) return 1; if (s.length() == 1 || x.length() == 1){ if (s.substring(0,1).equals(x.substring(0,1))){ s.replaceFirst((x), " "); return 1 + countSubstring(s.substring(1), x); } else { return 0 + countSubstring(s.substring(1), x); } } return countSubstring(s.substring(0,1), x) + countSubstring(s.substring(1), x); } public class Main { public static void main(String[] args) {...

T/F 11. A recursion will still be replaced by an iteration and the other way around.

Which of the following statement(s) is/are correct about recursion? Group of answer choices A.indication of good use of recursion: difficulty to trace down the sequence of recursive calls B.gives cleaner code but has high cost C.never be used as substitute for a simple ‘for’ loop D.bad idea to use it to evaluate simple mathematical functions. E.All of the above

Determine the output of the following recursive function when n = 64. (show your working/steps) int func (int n) { if (n ==1) return 0 else return 2 + func ( ) }

Written explaination required

in kotlin Write two versions of a recursive palindrome check function. One version should have a block body, and the other should have an expression body. Review the lecture slide about the substring function first. Use this algorithm: if the length of the string is less than 2, return true else if the first and last characters are not equal (!=) return false else return the result of a recursive call with the substring from the second character (the one at index 1) to the second to last character. Use a main that uses a loop to test the palindrome function using this list of strings: val ss = listOf("", "A", "AA", "AB", "AAA", "ABA", "ABB", "AAAA", "AABA", "ABBA", "ABCBA", "ABCAB")

Can I get help in racket please. Please do not solve in any other programs/language. When writing the following recursive functions, use only car/first, cdr/rest and cons functions. Do not use any built-in functions, except expt. 4. Write a recursive function, sumofSqr, that that will return the sum of the squares of the first N natural numbers. (sumofSqr 3) (sumofSqr 10) ===> 385 (sumofSqr 0) ===> 14 (12 + 22 + 32 ) ===> 0 5. Write a recursive function, mult5, at will return how many numbers in the list are multiples of 5. (mult5 '(60 22 13 25) ===> 2 (mult5 '(5) ===> 1 (mult5 '() ===> 0 6. Write a recursive function, getlast, that will return the last element in a list. If the list is empty, return the string "empty list". 7. Write a recursive function, countdown, that takes any non-negative integer start as its argument returns a list of all the positive integers less than or equal to start, in descending order: (countdown 5) ===> (5 4 32 1) (countdown 1) ===> (1) (countdown 0) ===>...

How do I calculate the minimum velocity and maximum height using recursion and code to ask the user to guess a minimum velocity and maximum height, which the code should use as start points

Write a recursive algorithm with the following prototype: int add (int x, int y); that returns x if y is 0; and adds x to y otherwise. THE FUNCTION MUST BE RECURSIVE. (hint: the base case should involve a test for y being 0; recursive case should reduce y towards 0)
