Everything about hash data structure you should know in 2023

A hash is a data structure that maps keys to values.

A hash table is an efficient data structure for storing and retrieving data.

[{"selector":"#anim-7f7a882b-0d45-48a5-8fc5-56b94cfbaf0d [data-leaf-element=\"true\"]","keyframes":{"transform":["translate(0%, 0%) scale(1.5)","translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}] [{"selector":"#anim-151d3025-e820-4875-b657-b2b5f36884f0","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-44f87408-e4c3-4f9d-ba14-feee3c128bbc","keyframes":{"transform":["translate3d(0px, 180.64240%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

Hash works by transforming the key using a hash function into a hash, which is then used to index an array

[{"selector":"#anim-c9d80c0c-e61e-483b-82d8-efacd300c9ac [data-leaf-element=\"true\"]","keyframes":{"transform":["translate(0%, 0%) scale(1.5)","translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}] [{"selector":"#anim-09b45ae3-06b0-44bf-a5b7-bd3c4abf7094","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-3139bf08-f35d-4cde-92c9-b2490249873a","keyframes":{"transform":["translate3d(0px, 154.79641%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

Hash tables can be implemented using a variety of data structures, including arrays, linked lists, and binary trees.

[{"selector":"#anim-86e2ef23-d059-4d1a-b2d9-eadfd77ce59a [data-leaf-element=\"true\"]","keyframes":{"transform":["translate(0%, 0%) scale(1.5)","translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}] [{"selector":"#anim-42589f2f-4266-400d-92d7-fb6c1b128220","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-c41d4242-9966-4be5-b387-4f671d323679","keyframes":{"transform":["translate3d(0px, 154.79641%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

One disadvantage of hash tables is that they can suffer from collisions, which occur when two different keys are mapped to the same hash

[{"selector":"#anim-413dba21-756e-4e1e-97b8-4fe7aefca109 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate(0%, 0%) scale(1.5)","translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}] [{"selector":"#anim-dd53bdc6-aab5-4847-95fa-99038580c5bb","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-ed2276e9-849e-4ff5-8723-fdcb2f7104b6","keyframes":{"transform":["translate3d(0px, 144.44442%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

There are various strategies for handling collisions, including separate chaining and open addressing.

[{"selector":"#anim-f4317e2e-34e6-4c36-b8fd-fbb256309537 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate(0%, 0%) scale(1.5)","translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}] [{"selector":"#anim-6038d38d-4ffd-4e19-810a-3441c4fb03fa","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-3ca18931-c4e3-4db6-ba4d-47c4a82c6374","keyframes":{"transform":["translate3d(0px, 174.05106%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

Hash functions transform keys into hashes using a mathematical operation and the size of the array.

[{"selector":"#anim-010e7957-585a-469f-954c-6d901b25b9c9 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate(0%, 0%) scale(1.5)","translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}] [{"selector":"#anim-1f6b445e-edcd-4dc4-a081-f3e9cc5e1b86","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-2d8cad28-bffe-4f68-8aeb-0f62d2149e84","keyframes":{"transform":["translate3d(0px, 203.29867%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]
