Solve problems that are commonly asked in C++ coding interviews related to common data structures.

Ace the C++ Coding Interview

Data structures are among the fundamentals of computer science and are often a core decision in developing efficient programs. They are categorized as a vital benchmark of computer science knowledge when it comes to industry interviews. This module contains a detailed review of common data structures in C++. We'll also become well-equipped with different data structures by implementing them.
By the end of this module, we'll have expertise in solving problems in data structures.

Data Structures


# Statement

Given the `head` of a singly linked list, remove any duplicate nodes from the list in place, ensuring that only one occurrence of each value is retained in the modified list.

**Constraints:**

Let `n` be the number of nodes in a linked list.

* $0 \leq$ `n` $\leq 500$
* $-5000 \leq$ `Node.value` $\leq 5000$

# Examples


Try to solve the Remove Duplicates from Linked List - Hashing problem.
