I am trying to make a tree data structure with c++. Originally I tested with int data, it was going fine. However, when I try to use a string data type, it keeps showing an unhandled exception. It said read access violation, this was 0x5D. I don’t know what is causing the error. The complete ..

Essentially, I have a tree class and a node class. I inserted nodes into the tree, and now I want to be able to delete certain nodes. So this is what I came up with, it cascades the child elements upwards. Basically, when I reach the bottom, I set those values to -999. Then I ..

I am creating Binarytree up to level four. Given inputs: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 I am using Queue to create level. These are the data types that I have declared. #include<bits/stdc++.h> using namespace std; struct treeNode{ struct treeNode *lc; int data; struct treeNode *rc; ..

I need to traverse a binary search tree and find the nth item, I’m able to successfully traverse the tree, however when I try to implement a limit, or end point, to stop at the nth item–returning it’s value, I can’t get my counter to increment. I’ve tried about fifty different ways to get the ..

I am working on a C++ code to find out the number of leave node in a binary tree using array input my code is: int leaf(int data[],int size) { int result = 0; for (int i = 0; i <= size; i++) { if (data[i] == -1) i++; if (((data[(2*i)+1] == -1) && (data[(2 ..

I have this getTreeLevel function, which works perfectly. void getTreeLevel(int level, int * size, Node* current, Node** result) { if (current == NULL) { return; } if (level > 0) { getTreeLevel(level – 1, size, current->left, result); getTreeLevel(level – 1, size, current->right, result); } if (level == 0) { cout << "Get Level Tree: Adding ..

Given a length and a binary tree of characters, say: a / b c I’m trying to print out all combinations of words. Example of word size 2, the combinations of words would be: aa, ab, ac, ba, bb, bc, ca, cb, cc. I was able to figure out how to print the tree if ..

I’m trying to solve the problem of Vertical Order Traversal of Binary Tree using map and queue. I did solve it using a recursive way, but I’m not getting the same answer using the iterative way. 10 / 7 4 / / 3 11 14 6 Approach : First I declared an integer that stores ..
