Given an input string, a non-empty substring subs, and a non-negative number n, compute recursively and return true if and only if at least n copies of subs occur in the string, possibly with overlapping. Do not use loops (do not write for or while anywhere in your code). Do not use any regular expressions and methods such as matches, split, replaceAll. Test case 1: checkSubstring("abcxxxxabc", "abc", 2) true Test case 2: checkSubstring("abcxxxxabc", "abc", 3) → false Test case 3: checkSubstring("ababaxxxaba", "aba", 3) true

Given a long string use recursion to traverse the string and replace every vowel (A,E,I,O,U) with an @ sign. You cannot change the method header. public String encodeVowels(String s){ // Your code here }
this should be done in C Our method will involve analyzing a string and picking the 5 most common letters in that string. We will then compute how far each of these is from the letter ‘e’. We will then produce 5 possible decryptions of the string by: Decryption 1 will be from comparing how far the most popular letter is from the letter “e” Decryption 2 will be from comparing how far the second most popular letter is from the letter “e” Decryption 3 will be from comparing how far the third most popular letter is from the letter “e” Decryption 4 will be from comparing how far the fourth most popular letter is from the letter “e” Decryption 5 will be from comparing how far the fifth most popular letter is from the letter “e”

The factorial of a positive integer n —which we denote as n!—is the product of n and the factorial of n 1. The factorial of 0 is 1. Write two different recursive methods in Java that each return the factorial of n. Analyze your algorithm in Big-Oh notation and provide the appropriate analysis, ensuring that your program has a test class.

A maze is a two dimensional array of chars. Walls are represented as '#'s and ' ' are empty squares. The maze entrance is always in the first row, second column (and will always be an empty square). There will be zero or more exits along the outside perimeter. To be considered an exit, it must be reachable from the entrance. The entrance is not an exit.Here are some example mazes:mazeA7 9# # ###### # # ## # # #### # ## ##### ## ########## RequirementsWrite a MazeSolver class in Java. This program needs to prompt the user for a maze filename and then explore the maze. Display how many exits were found and the positions (not indices) of the valid exits. Your program can display the valid exits found in any order. See the examples below for exact output requirements. Also, record…
Review Loops Write a java program to ask three people three questions about name, number of courses, and number of credit hours. Also, print result in columns as below. Note: the input.nextInt() method reads only the integer value from input buffer.The "\n" is still staying in the input buffer. If you continue reading with input.nextLine(),you will receive the "\n" and CPU will not wait for any input. To fix this problem, you addthe statement input.nextLine() to flush out the "\n" from the input buffer.
Given a list of integers, you want to know whether it is possible to divide the integers into two sets, so that the sums of the two sets are the same. Every integer must be in one set or the other. Write a recursive helper method that takes any number of arguments you like, and make the initial call to your recursive helper method from equalSum(). Do not use any loops or regular expressions. Test case 1: equalSum([2, 3, 5]) true Test case 2: equalSum([2, 2, 5]) false
Given a string, write a method that returns the number of occurrences of substrings "baba" or "mama" in the input string recursively. They may overlap. Do not use any loops within your code. Do not use any regular expressions and methods such as matches, split, replaceAll. "Maa mana, Test case 1: countBabaMama ("aba babaa amama ma") 2 Test case 2: countBabaMama ("bababamamama") 4
