Those are JAVA Programs. Please
write them in recursions , it requires the methods have to be
recursive(I understood how to write them by using for loop).
Please don't use
any syntax beyond chapter of Recursion. I only covered the
materials to recursions and the materials before recursion chapter.
Appreciated!

Please write in java Write a main program that runs the following two recursive methods demonstrating that they work. #1) Write a recursive method writeSquares that accepts an integer n and prints the first n squares with the odd squares in decending order, followed by the even squares in acending order. For example • writeSquares(8): prints . 49 25 9 1 4 16 36 64 • writeSquares(11); prints 121 81 49 25 9 1 2 16 36 64 100 •...
Please i need programs in C 32) Write a function that, given a string, a width, and an empty string for output, centers the string in the output, centers the string in the output area. The function is to return 1 if the formating is successful and 0 if any errors, such as string length greater than width, are formed. 35) Write a function called newStrCmp that does the same job as strcmp. The declaration for your functions is to...
can someone please help me with this. I need to use java. Recursion Write and run a program that reads in a set of numbers and stores them in a sequential array. It then calls a recursive function to sort the elements of the array in ascending order. When the sorting is done, the main function prints out the elements of the newly sorted array Hint: How do you sort an array recursively? Place the smallest element of the array...
Create two Java classes called Recursive, RecursiveDemo. Write four methods a- int sum_sqr_rec(stack<int> stk) which will receive a stack of "int" and output the sum of the squares of the elements in the stack. b- int plus_minus_rec(stack<int> stk) which will receive a stack of "int" (example: {a,b,c,d,e,f,g,h,i,j}) and output the sum of the elements in the stack as follows: a - b + c - d + e - f + g - h + i -j c- void prt_chars_rev_rec(stack<char>...
3. Write Java methods to accomplish each of the following Write a method named simpleAry which accepts and return nothing. It creates an array that can hold ten integers. Fill up each slot of the array with the number 113. Then, display the contents of the array on the screen. You must use a loop to put the values in the array and also to display them. Write a method named sury which accepts an array of type double with...
write in java 1. Assume the availability of a method named makeLine that can be passed a non-negative integer n and a character c and return a String consisting of n identical characters that are all equal to c. Write a method named printTriangle that receives two integer parameters n and k. If n is negative the method does nothing. If n happens to be an even number, itsvalue is raised to the next odd number (e.g. 4-->5). Then, when k has the value zero, the method prints...
Assignment 6, Merge Arrays (java) Instructions In this assignment, you will write a program which merges two arrays of positive integers and removes any duplicate entries. Your program will first ask for a valid length which must be an integer which is 10 or greater. The program should continue to ask until a valid length is entered. The program will then create two arrays of the length entered, fill these with random integers between 1 and 100 inclusive, and print...
JAVA LANG PLEASE: I have follwed these below guidelines but when i run my queue test it is not executing but my stack is working fine, can you fix it please! MyQueue.java Implement a queue using the MyStack.java implementation as your data structure. In other words, your instance variable to hold the queue items will be a MyStack class. enqueue(String item): inserts item into the queue dequeue(): returns and deletes the first element in the queue isEmpty(): returns true or false...
can i get some help with this program CMPS 12B Introduction to Data Structures Programming Assignment 2 In this project, you will write a Java program that uses recursion to find all solutions to the n-Queens problem, for 1 Sns 15. (Students who took CMPS 12A from me worked on an iterative, non-recursive approach to this same problem. You can see it at https://classes.soe.ucsc.edu/cmps012a/Spring l8/pa5.pdf.) Begin by reading the Wikipcdia article on the Eight Queens puzzle at: http://en.wikipedia.org/wiki/Eight queens_puzzle In...
