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 1 \ 2 \ 5 / \ 3 6 \ 4 Sample Output 1 2 3 4 5 6
Solution :
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)))

Waiter
You are a waiter at a party. There is a pile of numbered plates. Create an empty answers array. At each iteration, i, remove each plate from the top of the stack in order. Determine if the number on the plate is evenly divisible ith the prime number. If it is, stack it in pile Bi. Otherwise, stack it in stack Ai. Store the values Bi in from top to bottom in answers. In the next iteration, do the

A queue is an abstract data type that maintains the order in which elements were added to it, allowing the oldest elements to be removed from the front and new elements to be added to the rear. This is called a First-In-First-Out (FIFO) data structure because the first element added to the queue (i.e., the one that has been waiting the longest) is always the first one to be removed. A basic que
