Join Raghavendra Dixit for an in-depth discussion in this video Resolving collisions through chaining, part of Introduction to Data Structures & Algorithms in Java.
- [Instructor] One of the ways to resolve collisions…can be not to insert the data directly into the array slot.…Rather, we can use a list,…a linked list kind of data structure for each slot.…So even if multiple keys map to the same slot,…the records can be stored as a linked list.…Here, each record contains the key,…as well as the satellite data in a node of a linked list.…So if the hash function h,…when applied to keys K2 and K3,…evaluate to a single integer value i,…we can store the data associated with keys K2 and K3…as a linked list at the same array index i.…
So this method of resolving collisions…is called the method of chaining.…Now what would be the worst-case time complexity…of finding the item if we use chaining?…Think about what will happen in the worst case.…Well, in the worst case,…all the keys may map to a single slot, right?…That is, when we hash any key,…we get the same value of the index…where the record should be inserted.…So all the records have been stored…in one single linked list.…
So if you have to find the record…
