Your program may print any debugging information that you choose, but the last line of your output should indicate whether or not the tree satisfies the red-black tree properties. Your program must echo the tree recursively from your data structure. Likewise, your code for reading the tree must be recursive.

See explaination

Explanation:

/* Program to check if a given Binary Tree is balanced like a Red-Black Tree */

#include <stdio.h>

#include <stdlib.h>

struct Node

{

int key;

struct Node *left, *right;

};

/* utility that allocates a new Node with the given key */

struct Node* newNode(int key)

{

struct Node* node = (struct Node*)malloc(sizeof(struct Node));

node->key = key;

node->left = node->right = NULL;

return (node);

}

int max(int a,int b)

{

if(a>b)return a;

else return b;

}

int min(int a,int b)

{

if(a>b)return b;

else return a;

}

// Returns returns tree if the Binary tree is balanced like a Red-Black

// tree. This function also sets value in maxh and minh (passed by

// reference). maxh and minh are set as maximum and minimum heights of root.

int isBalancedUtil(struct Node *root, int maxh, int minh)

{

// Base case

if (root == NULL)

{

maxh = minh = 0;

return 1;

}

int lmxh, lmnh; // To store max and min heights of left subtree

int rmxh, rmnh; // To store max and min heights of right subtree

// Check if left subtree is balanced, also set lmxh and lmnh

if (isBalancedUtil(root->left, lmxh, lmnh) == 0)

return 0;

// Check if right subtree is balanced, also set rmxh and rmnh

if (isBalancedUtil(root->right, rmxh, rmnh) == 0)

return 0;

// Set the max and min heights of this node for the parent call

maxh = max(lmxh, rmxh) + 1;

minh = min(lmnh, rmnh) + 1;

// See if this node is balanced

if (maxh <= 2*minh)

return 1;

return 1;

}

// A wrapper over isBalancedUtil()

int isBalanced(struct Node *root)

{

int maxh, minh;

return isBalancedUtil(root, maxh, minh);

}

/* Driver program to test above functions*/

int main()

{

struct Node * root = newNode(10);

root->left = newNode(5);

root->right = newNode(100);

root->right->left = newNode(50);

root->right->right = newNode(150);

root->right->left->left = newNode(40);

isBalanced(root)? printf( "Balanced RBT" ): printf( "Not Balanced Tree");

return 0;

}

solution:

this situation is called an ip conflict.

data from a server is sent in small bits called packets. in an ip conflict, some packets will end up in one computer while some other packets will end up in another computer.

so…overall none of the computers get the data as the original message or picture being sent by the server cannot be retrieved with only half the packets. so it will show up as an error.

thus the final answer is d.
