Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which word describes lot of collisions with using hashing?
A
contiguous
B
traffic
C
clustering
D
mutable
Explanation: 

Detailed explanation-1: -This type of hash collision is called a general hash collision.

Detailed explanation-2: -Definition: A collision occurs when more than one value to be hashed by a particular hash function hash to the same slot in the table or data structure (hash table) being generated by the hash function.

Detailed explanation-3: -Hashing in data structure falls into a collision if two keys are assigned the same index number in the hash table.

Detailed explanation-4: -There are different types of probing that take place when a hash collision happens and this method is implemented. Some types of probing are linear probing, double hashing, and quadratic probing. Open Addressing is also known as closed hashing.

Detailed explanation-5: -As we have discussed previously, there will be a possibility that one key is used by two values or more, since we map a big key to a small key. This situation is called a collision, where there is another key that will be mapped to an occupied slot.
