Find the largest number in a binary tree
Answers were Sorted based on User's Feedback
Answer / guest
Well..it's not a binary search tree.So we need to traverse
entire binary tree and check with the all node elements and
find the max value.
struct node
{
int data;
struct node *l;
struct node *r;
};
typedef struct node *nd;
int maximum(nd root)
{
static int max;
nd cur = root;
if(cur!=NULL)
{
if(cur->data>max)
max=cur->data;
maximum(root->l);
maximum(root->r);
}
return max;
}

There is a difference between a binary tree and a binary search tree.
A binary tree isn't organized in any sense. The values of it's nodes can be random and have no relationship to each other.
Here is a method for finding the biggest node on a binary tree.
typedef struct node {
int value;
struct tree *right;
struct tree *left;
} Node;
int biggest_node(Node *node)
{
int biggest_left, biggest_right;
biggest_left = node->left ? biggest_node(node->left) : node->value;
biggest_right = node->right ? biggest_node(node->right) : node->value;
if(node->value < biggest_left && node->value < biggest_right)
return biggest_left > biggest_right ? biggest_left : biggest_right;
else if(node->value < biggest_right)
return biggest_right;
else if(node->value < biggest_left)
return biggest_left;
else
return node->value;
}

int maxOfTree(tree * t)
{
//if tree is empty then it will return -99
if(t==null){return -99;}
else
{
int temp ;
temp=max( maxOfTree(t->left), maxOfTree(t->right));
return( max( t->info , temp ) );
}

Answer / bharat pandey
The Largest Node in the Binary tree is the Rightmost node
of the tree.
Hence we would traverse the Tree Till The Rightmost child
of the node is traversed.
the code is as follows:
#include<stdio.h>
#include<conio.h>
struct node
{
int data;
struct node *left,*right;
}*tree;
struct node* MAX(struct node* q)
{
struct node* temp;
while(q->right!=NULL)
{
temp=q;
q=q->right;
}
return temp;
}
this algorithm will find the largest element of the tree in
o(log n).

write a program to count the number the same (letter/character foreg: 's') in a given sentence.
#ifdef something int some=0; #endif main() { int thing = 0; printf("%d %d\n", some ,thing); }
struct Foo { char *pName; char *pAddress; }; main() { struct Foo *obj = malloc(sizeof(struct Foo)); clrscr(); obj->pName = malloc(100); obj->pAddress = malloc(100); strcpy(obj->pName,"Your Name"); strcpy(obj->pAddress, "Your Address"); free(obj); printf("%s", obj->pName); printf("%s", obj->pAddress); } a. Your Name, Your Address b. Your Address, Your Address c. Your Name Your Name d. None of the above
char inputString[100] = {0}; To get string input from the keyboard which one of the following is better? 1) gets(inputString) 2) fgets(inputString, sizeof(inputString), fp)
main() { int i, j; scanf("%d %d"+scanf("%d %d", &i, &j)); printf("%d %d", i, j); } a. Runtime error. b. 0, 0 c. Compile error d. the first two values entered by the user
#include<stdio.h> main() { const int i=4; float j; j = ++i; printf("%d %f", i,++j); }
main() { char name[10],s[12]; scanf(" \"%[^\"]\"",s); } How scanf will execute?
main() { int i=5; printf("%d",++i++); }
main() { int i=3; switch(i) { default:printf("zero"); case 1: printf("one"); break; case 2:printf("two"); break; case 3: printf("three"); break; } }
Write a Program that Inputs 10 Numbers in an Array and Show the Maximum Number
How do you create a really large matrix (i.e. 3500x3500) in C without having the program crash? I can only reach up to 2500. It must have something to do with lack of memory. Please help!
What is the output for the following program main() { int arr2D[3][3]; printf("%d\n", ((arr2D==* arr2D)&&(* arr2D == arr2D[0])) ); }
