WebMay 17, 2016 · The hash table stores a free_head index of its own which models a stack without storing a stack (the memory double overs as either an index to the next free element or data for an element). That leaves the vacant spots freed to be reclaimed on subsequent insertions. – user4842163 Dec 7, 2024 at 16:03 WebIn chaining, if a hash function produces the same index for multiple elements, these elements are stored in the same index by using a doubly-linked list. If j is the slot for multiple elements, it contains a pointer to the head of the list of elements. If no element is present, j contains NIL. Collision Resolution using chaining
