Below is the Java program to reverse a string using recursion ? Open Compiler public class StringReverse { public String reverseString(String str){ if(str.isEmpty()){ return str; } else { return reverseString(str.substring(1))+str.charAt(0); } } public static void main(String[] args)...
As we can see, when thelistobject contains only one element (7), we stop the recursion and then start executinglist.add(value)from the bottom. That is, we first add 6 to the end of the list, then 5, then 4, and so on. In the end, the order of the elements in the list has ...

Java Implementation The algorithm involves the use of the recursive reverse function which works on the above induction hypothesis and recursion. It basically uses the substring function of strings and concatenates the string in every recursive call. import java.util.*; public class Main { static St...
That's all abouthow to reverse a singly linked list in Java without using recursion. Yes, we have not used recursion in this solution, instead, we have used iteration. You can see the while loop insidethe reverse()method. Btw, if you get this question asked in the real interview, you...
Java program to reverse a string using stacks - In this article, we will understand how to reverse a string using stacks. String is a datatype that contains one or more characters and is enclosed in double quotes(“”). The stack is a linear data struct
