I am still new to stacks and recursion and am trying to implement two functions using recursion to get the maximum element in a stack and copying one stack into the other but it keeps repeating some elements and i dont understand why!!
I have a program that consist of a postfix calculator for a class assigment, my program is basically done, however I am missing how to loop through the stack and print each element of it. My output is suppose to look something like this:
Token: 4+5 (my token would be the infix expression that the user inputs)
output:45+ (my output would be the postfix expression)
Stack(bottom to top) :empty + + empty (This is suppose to be the process of the stack, but I do not know how to get this values to print out)
and I already have the token and output part, however I do not know how could I get the stack values, in order to print them out.
To construct and write down algorithm of determination of the sum of squares of consecutive integers with recursion use. I tried to do something:
public static int RecSumSquare(int x, int n) { if (n < 0) throw new ArgumentException("n should be greater than zero"); if (n == 0) return 0; else return x*x+RecSumSquare(x, n - 1); }
But I don't know as the beginning and the end of this algorithm will look.
So the task is to find the node with minimum value of a binary tree (not binary search tree). the input is the pointer to the root of the tree. and i cannot make recursion work when i do if conditions. here is what i have Code: /*function 3-takses as input the pointer to the root of the tree and returns a pointer to the node with the minimum value*/
CPPtr minimumvalue(CPPtr SP){ CPPtr min = NULL; //node of minimum value if(SP== NULL){ // if there is a node, begin comparing return NULL; } else{ if(SP->data<SP->left->data){ //if the node has smaller value than its left child min = SP; //update node of minimum value

no matter where i call my function i get errors like unhandled exception at some memory. how to use recursion in this?
I have this problem set that has to use recursion to permutate scores. I have read in all the numbers and have tested that it works . l have also attached what I have so far. Here is what I think I need to do:I have to pass the structs into this permutation algorithm that is here:
Code: #include <stdio.h> void ListPermutations(char str[]); void RecursivePermute(char str[], int k); void ExchangeCharacters(char str[], int i, int j);
It seems that boost's file recursion requires that the file using the recursion must be in the include path. This makes using file recursion in a library header a problem as libraries may be located in a subdirectory of an include path (which is minor since the programmer can state the subdirectory in the recursive file call as long as it is not relative to the calling file). I also found it a problem when the main compile directory isn't in the compile path.

So i have a program it works which takes in a word reverses it prints it out. BUT! the problem is that the program is without recursion. convert the function into recursion.
I am trying to print an outline. My code works up to a depth of 3. (The depth is the number of subsections - so 3 would be section 1, section 1.A, and section 1.A.1). It also works for a width (number of sections and each type of subsection) of 26, where it is capped. However, to get a larger depth, it would involve many more loops. Not only is that terrible code, it also freezes up the terminal I'm working on. I believe recursion would make it much nicer, but I'm struggling to grasp the idea when using a string (I understand when it is a number).
#include <stdio.h> int sec(int width, int snum) { char section[100]; sprintf(section, "Section ");
I have a linked list I made and am practicing a simple recursion function sum() which returns the sum of all numbers in each node of the list. Here is my sum() function:
int sum(ListNode *ptr){ if (ptr->next) return (ptr->num + sum(ptr->next)); else return(0); }
where the initial arg passed through the ListNode * parameter is my head node (with null value). The output is fine until that point, then the program locks up and I get the "...has stopped working" error.
I have been asked to write three functions for a Liked List that can add remove and reverse the elements of the Linked List. Now, I have done the add function and It is displaying the elements properly using recursion function. But My removal function is not working and I tried all the possible logic I can think of, I dont know, where did I make mistakes.
This is My class for the Linked List
#ifndef __Linked_Lists_Recursive_function_Implementation___NumberList__ #define __Linked_Lists_Recursive_function_Implementation___NumberList__ #include <iostream> using namespace std;
I am trying to input a recursion method. The code compiles, however, it is only giving me a value of 1. I am wanting the value of 5 when it is compiled. Why is this?
#include <iostream> using namespace std; int number(int x) { if (x == 1)
How to print to the screen the value of n after it has been multiplied.
For example: if I use cout << "n: " << n << " power: " << power << " "; I
can see the variable "power" decrementing by 1, but I don't see the variable "n" incrementing with its new value after it has been multiplied by n * n.
#include <iostream> using namespace std; typedef unsigned short int USHORT; typedef unsigned long int ULONG;
I'm trying to write a program that converts a decimal number to a binary one. I have most of the program written, but I am having a little bit of trouble. Whenever I enter a decimal number, the program will convert it correctly to binary, however, the last number is not included in the conversion. EX: Converting 37 into binary (0100101) yields 010010 when entered into the program. BTW the program must utilize recursion to achieve this goal.
#include <iostream> using namespace std; void decToBinary(int num1); int main() { int num1;
I am having to write a program that takes 2 sorted linked lists (x and y) and merge those to sorted into a third one (z). This has to be done via recursion. I think I am close but there is a logic error.
