Tree: Inorder Traversal


Problem Statement :


In this challenge, you are required to implement inorder traversal of a tree.

Complete the inorder  function in your editor below, which has 1 parameter: a pointer to the root of a binary tree. It must print the values in the tree's inorder traversal as a single line of space-separated values.

Input Format

Our hidden tester code passes the root node of a binary tree to your $inOrder* function.

Constraints

1 <= Nodes in the Tree <= 500
       

Output Format

Print the tree's inorder traversal as a single line of space-separated values.

Sample Input

                            Solution in C :

In Java :



void Inorder(Node root) {
    if (root == null) { return; }
    Inorder(root.left);
    System.out.print(root.data + " ");
    Inorder(root.right);
}



In C++ :


/* you only have to complete the function given below.  
Node is defined as  

struct node
{
    int data;
    node* left;
    node* right;
};

*/

void Inorder(node *root) {
    if (!root) return;
    Inorder(root->left);
    printf("%d ", root->data);
    Inorder(root->right);
}



In C :



/* you only have to complete the function given below.  
node is defined as  

struct node {
    
    int data;
    struct node *left;
    struct node *right;
  
};

*/
void inOrder( struct node *root) {
  if(root==NULL){
      return;
  }
  else{
      inOrder(root->left);
      printf("%d ",root->data);
      inOrder(root->right);
  }
}




In python 3 :


"""
Node is defined as
self.left (the left child of the node)
self.right (the right child of the node)
self.data (the value of the node)
"""

def _preOrder(root, acc):
    if root:
        _preOrder(root.left, acc)
        acc.append(root.data)
        _preOrder(root.right, acc)

def inOrder(root):
    acc = []
    _preOrder(root, acc)
    print(" ".join(map(str, acc)))
    #Write your code here

You are given Q queries. Each query consists of a single number N. You can perform any of the 2 operations N on in each move: 1: If we take 2 integers a and b where , N = a * b , then we can change N = max( a, b ) 2: Decrease the value of N by 1. Determine the minimum number of moves required to reduce the value of N to 0. Input Format The first line contains the integer Q.

Suppose there is a circle. There are N petrol pumps on that circle. Petrol pumps are numbered 0 to (N-1) (both inclusive). You have two pieces of information corresponding to each of the petrol pump: (1) the amount of petrol that particular petrol pump will give, and (2) the distance from that petrol pump to the next petrol pump. Initially, you have a tank of infinite capacity carrying no petr

Find the Running Median

The median of a set of integers is the midpoint value of the data set for which an equal number of integers are less than and greater than the value. To find the median, you must first sort your set of integers in non-decreasing order, then: If your set contains an odd number of elements, the median is the middle element of the sorted sample. In the sorted set { 1, 2, 3 } , 2 is the median.
