 The goal will be to have a data structure that can safely allow readers to do the traversal even if writer has deleted the node. Hazard pointers will be used to achieve that.

 ## Hazard Pointer (https://ieeexplore.ieee.org/document/1291819)
 
 Hazard Pointer is a garbage collection technique which allows concurrent access to an object in a thread even when it might be deleted by other threads. For example, thread A might be deleting a node and at the same time another thread B can have access to that same node. If thread A frees the memory, then thread B will crash because it is trying to access invalid address.
