Rearrange Array in Maximum-Minimum form

Given a sorted array of positive integers, rearrange the array alternately i.e first element should be the maximum value, second minimum value, third-second max, fourth-second min and so on. Naive Solution: Here we will use an auxiliary array to store the elements in correct order. For even indices of the array  Large numbers from the given array are added. For odd indices small numbers are added. Code: import java.util.*; public class Test{        public static void main(String[] args) {          Scanner in = new Scanner(System.in);     int[] a = {1,2,3,4,5,6,7,8,9};     int n = a.length;     int[] temp = new int[n];     int small = 0;     int large = n-1;     for(int i=0; i<n; i++){         if(i%2 == 0){             temp[i] = a[large--];         }  ...

Find Maximum in Binary Tree

Problem link Recursion Steps: If the node is null return Integers min value Maximum is the max of node data, left subtree and right subtree. Code: package may; public class MaximumInTree {         Node root;         int findMax(Node node){         if(node == null)             return Integer.MIN_VALUE;                 return Math.max(Math.max(node.data, findMax(node.left)), findMax(node.right));     }         public static void main(String args[])     {         MaximumInTree tree = new MaximumInTree();         tree.root = new Node(2);         tree.root.left = new Node(7);         tree.root.right...
