Recursion: Java-recursion is a mechanism in which a method continuously calls itself. In java, a method which calls itself is called recursive method. Using this mechanism, some problems can be solved easily. For example, problems like, Tower of Hanoi(TOH), Inorder/Preorder/Postorder Tree Travels, DFS of Graph are solved using recursion. Syntax of recursive methods, //define recursive method returntype methodname () { //code to be executed //calling same method methodname(); } In the above code, a method “methodname()” is a recursive method because, in the definition, this method calls by itself.

Question

Chapter 13, Problem 3RE

Program Plan Intro

Recursion:

Java-recursion is a mechanism in which a method continuously calls itself.

In java, a method which calls itself is called recursive method.

Using this mechanism, some problems can be solved easily.

For example, problems like, Tower of Hanoi(TOH), Inorder/Preorder/Postorder Tree Travels, DFS of Graph are solved using recursion.

Syntax of recursive methods,
//define recursive method

returntype methodname()

{

//code to be executed

//calling same method

methodname();

}

In the above code, a method “methodname()” is a recursive method because, in the definition, this method calls by itself.
