Below is the Java program to implement binary search on char array ? Open Compiler import java.util.Arrays; public class Demo { public static void main(String[] args) { char c_arr[] = { 'b', 's', 'l', 'e', 'm' }; Arrays.sort(c_arr); System.out.print("The sorted array ...
Insert operation adds a new node in a binary search tree. The algorithm for the binary search tree insert operation is given below. Insert(data) Begin If node == null Return createNode(data) If(data >root->data) Node->right = insert(node->left,data) ...
If the value is found, we return the value so that it gets propagated in each recursion step as shown in the image below. If you might have noticed, we have called return search(struct node*) four times. When we return either the new node or NULL, the value gets returned again and ...
That left or right child node becomes the parent's new left or right child through recursion (line 7 or 9). Case 3: Node has both left and right child nodes. The in-order successor is found using the minValueNode() function. We keep the successor's value by setting it as the ...

Challenge 2: Non-Recursive Search Does recursion make your brain hurt? No worries, you can always perform the same task in a non-recursive way. Re-implement binarySearch using a while loop. Challenge 3: Searching for a Range Write a function that searches a sorted list and finds the range...
