Thank you for contributing to Algorithms/java, we are happy to merge your pull request but first, it needs to fix:

Can you please:

• move the algorithm directly into /traversals, or any folder that fit into the algorithm type, probably its already created, but if it not you can feel free to create a new folder.
• remove from the algorithms:

package algos.practice;

Recomendations:

If you are the author of those implementations, make sure to add your name on it! Following this template

/**
 * {Name of the algorithm} implementation in Java
 * 
 * @author: {you name}
 * @github: {your username}
 */

we are waiting for your changes

I have made the changes as per the suggestion in the comment.
