Create copy-list-with-random-pointer.java

[Tsurya06]

The Copy List with Random Pointer problem involves creating a deep copy of a linked list where each node has a next pointer and a random pointer (pointing to any other node or null). The solution uses a three-step approach: first, clone each node and place the clone next to the original; second, set the random pointers of each clone based on the original nodes' random pointers; finally, separate the original and cloned lists. This method efficiently creates the copied list with O(n) time complexity and O(1) auxiliary space.
