There is an array of numbers from 1 to 100 which are not in order. Sort the array in O(N) complexity.  
 

// implemented the function to sort any given array
function sortValues(arrofUnsorted){

var minimum = arrofUnsorted[0];
var maximun = arrofUnsorted[0];
var arrSorted = [];
var temp;

Given a binary tree, find the height of the binary tree. 

Expected: Input: Root node of the tree Output: Height of the tree.

public class BinaryTree {  
      
    //Represent the node of binary tree  
    public static class Node{  
        int data;  
        Node left;

Given an array, rotate the array to the right by k steps, where k is non-negative.
Expected:  Input: [1,2,7,8,9] & k=3 (3 steps) Output: [7,8,9,1,2] 

// implemented function to rotate the array in anticlockwise. 
function rotateRight(arrRotate, step){

//  adding the new elements to the end of the array based on the step value.
for (var i=0; i<step ; i++)
{
        arrRotate.push(arrRotate[i]);
