明白递归语句之前的语句都是顺序运行,而递归语句之后的语句都是逆序运行 package recursion; import java.util.Stack; public class Reverse_a_stack_using_recursion { /* Input stack: 3 2 1 Output stack: 1 2 3 */ public static void main(String[] args) { Stack<Integer> s = new Stack<Integer>(...
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)...
Next, let’s explore a couple of nice implementations: one using recursion and another using a simple loop. 4. Reversing aListUsing Recursion First, let’s implement our own list-reverse method using therecursiontechnique. First, let’s take a look at the implementation: public static <T> v...

Too Long; Didn't ReadAn easy way to solve the problem is through simple iteration by just using a for loop with i from index 0 to n/2 and then character interchanging with n-i. But here, we will look into the solution of the problem using recursion. It involves the idea to ...
// Rust program to reverse a number // using recursion fn reverse(num:i32, len:u32)->i32{ let x:i32 = 10; if len == 1{ return num; } else{ return (num % 10) * x.pow(len - 1) + reverse(num / 10, len-1); } } fn main() { let rs = reverse(1234,4); println!(...
Btw, if you get this question asked in the real interview, you would be most likely asked to reverse the linked list using recursion now. So, wait for another article to see that solution or check out theCracking the Coding Interviewbook, which contains a solution to this problem along wit...
