[FEATURE REQUEST] Basic Recursion

[Tuhinm2002]

What would you like to Propose?

I found Dynamic Programming is there but the basic Recursion is not there. Problems like finding power set or subsets can only be done using recursion. Recursion plays an crucial role for setting the strong foundation for Dynamic programming.

My test cases :

package com.thealgorithms.Recursion;

import static org.junit.jupiter.api.Assertions.assertEquals;

import org.junit.jupiter.api.Test;

import java.util.ArrayList;

public class SubsetsTest {

    @Test
    void subset(){
        String str = "abc";
        ArrayList<String> ans = new ArrayList<>();
        ArrayList<String> actual = new ArrayList<>();
        ans.add("abc");
        ans.add("ab");
        ans.add("ac");
        ans.add("a");
        ans.add("bc");
        ans.add("b");
        ans.add("c");
        ans.add("");

        Subsets.subset("",str,actual);
        assertEquals(ans.toString(),actual.toString());
    }
}

Issue details

There is no package for recursion and recursion problems like producing subsets and powerset

Hi @Tuhinm2002 , I would like to contribute to this. I am not able to understand what is required here. Can you explain it in a brief?

Thanks !!!

No its not an assignment. It is a feature request originally opened by me. First read contribution.md file before contributing

I guess @sujitgunjal is already working on it.

Yeah I created a PR with the name feat: recursion subsets added. Please review it. And after it gets merge I will complete the package all at once in the next PR. Because in this PR it is not possible to edit 😅
