I am trying to create a function to find the entry point of my map.But my program does not seem to be working correctly. I am trying to place a dot there because I will have to use recursion to fill up the whole map. But I'm not asking for the answer. I just need writing a function to locate the starting row for the first column of the maze (first non zero element). My code seems to have a bug in it when I try and call my function FindEntry. What I am trying to do is read in column by column until I can find the starting point and then place a dot there with ASCII character 249. This is my code so far:
I understand that I have to find the height by using _left->height() and _right->height() as long as it is not a null-pointer , each time I do this the values of _left and _right change. That way you can check if it is possible to go further down in the tree. I also have to use a counter to keep track of the number of layers at each side of the root. I don't understand how to implement it.
I wrote a program with a recursive() called finder. But it dose not work properly,at run time it becomes to a infinite status. How to detect the error at runtime. Here is the code.
#include<stdio.h> void finder(int x,int y); int tot;
[Code] ....
I think the error is the changing value of x after a round of for loop.
I am trying to create a recursive function that i can call on in order to take a user inputed base and exponent and give final answer this is what i have but im completely lost after this i dont even know how to continue. What i have so far
#include <iostream> using namespace std; int Exp(int x,int y){ if(base <= 1 || exp == 0) return 1; if(exp == 1) return base; int main(){ int number, exp;
[Code] .....
After i set the base situations im not sure how to get the function to make the function take the base to the exponent recursively.
Why my program is returning a negative number at the end...attached is the program:
/*Write a recursive function recursiveMinimum that takes an integer array and the array size as arguments and returns the smallest element of the array. The function should stop processing and return when it receives an array of 1 element.*/
#include <stdio.h> #include <time.h> #include <iostream> using namespace std; float recursiveMinimum (int ARRAY[], int n);
When I worked with Fibonacci it was pretty easy since I just had to decrement the next member for each step. I used the following:
#include <stdio.h> #include <stdlib.h> #define MAX 100 int fib(int n) { static int memorize[MAX] = {1,1}; if(memorize[n]) return memorize[n];
[Code] ....
My main problem is that I have no visual of the current function, as well as the fact that it takes the f(n+3) = f(n+2) + f(n+1) + f(n), whilist I've only got f(n) to begin with.
0. Base Case: If the number is one digit long, we don't want to erase it (by returning 0). Instead, riddle me this: When I have a one-digit number, what happens if I change all the 7's into 8's? Well, if the number is 7, it becomes 8, but otherwise it's unchanged.
1. Recursive Call: If the number is longer, then we strip off the last digit, figure out what the answer for the rest is (the recursive call on n/10), and then put the last digit back on the number when you're done.
Hint: You probably need to store the least digit (the n%10) and check if it's 7 separately.
#include <iostream> using namespace std; int removeFirst(int n) { if(n<10) return 0; return 10*removeFirst(n/10)+n%10;
I use rand function to generate a number which consists of 3-5 digits(e.134,1435,73463..). The user decides whether he wants a 3 digit,4 digit or 5 digit number.After that,the user tries to guess the number.Its like mastermind game.The user will enter a number (with the same amount of digits) and the program will calculate how many digits from the secret number he has found and also how many digits he has found in the correct position(e.if the generatir produces the number 32541 and the user tries the number 49581 the program should tell him that he found 3 digits (5,1,4) and 2 digits in the correct position(5,1)) so that after some tries he finds the secret number.My problem is with the functions so that i can compare the digit of each number,find the amount of same digits and the amount of digits in same position.
I have a function where i declared the number of elements in a vector alocated dynamically which returns the vector to the main function. The problem is how can i find the number of elements in main function? I tried length = sizeof(a) / sizeof(int) which gives me the same value, the value of the first element. Here's the code:
int* functie2 (void) { int* p; int c,i; printf("number of elements: "); scanf("%d",&c);
[Code]...
I know i could first read the value of c in main and then pass it thorugh parameter, but how can i do it the other way arround?I could also send the value of c allocating one more int value to the vector, but i don't want doing so.
Is there any way to programatically find if the given code is taking recursive approach or iterative apporaoch using concept of files in C programming.
How do you generate a random permutation of numbers from 0 to N without storing it in an array ? Note that duplicates are to be avoided so I can't use rand() calls to generate them. The problem I have is to partition N number of data points into k groups in random selection manner. I thought of random shuffling of indices using random_shuffle of stl but the indices need to be stored in an array. Is there a way to get N integers from [0..n] sorted in a random order, using which I can access a database ?
The recursive function is bolded, i got feedback and was told that the static variable made the function seem a lot like a iterative function but he did not say why.
Code: #define MAX 100 #include <string.h> #include <stdio.h> int checkPalindrome(char string[MAX]); int checkRecPalindrome(char string[MAX]);
the functions checks if the word is a palindrome like"level" "madam" etc. but with input "dfdfdfdffdfd" my recursive function fails.
Code:
/* main.c - Created on: Nov 9, 2013 - Author: Kaj P. Madsen*/ #define MAX 100 #include <string.h> #include <stdio.h> int checkPalindrome(char checkString[MAX]); int checkRecPalindrome(char checkString[MAX], int strLgt, int a); }
[code]....
results from "dfdfdfdffdfd" added some print to see that its the variables a and strLgt not functioning properly
Code:
dfdfdfdffdfd. The word is not a palindrome(iterative) strLgt: 11 a: 0 a: d strLgt: dstrLgt: 10 a: 1 a: f strLgt: fstrLgt: 9 a: 2 a: d strLgt: dstrLgt: 8 a: 3 a: f strLgt: fstrLgt: 7 a: 4
