Linear Probing in relation to Hash Tables ____
A
is checking the length of a Hash Table
B
is a process of going through each Index one by one looking for a desired value
C
Assigning the next empty key value to resolve a collision
D
a personal part of someones medical history
Explanation: 

Detailed explanation-1: -A hash collision occurs when the hash function maps a key into a cell that is already occupied by a different key. Linear probing is a strategy for resolving collisions, by placing the new key into the closest following empty cell.

Detailed explanation-2: -In this tutorial, we’ll learn about linear probing – a collision resolution technique for searching the location of an element in a hash table. Hash tables are auxiliary data structures that map indexes to keys.

Detailed explanation-3: -Hash collision is resolved by open addressing with linear probing. Since CodeMonk and Hashing are hashed to the same index i.e. 2, store Hashing at 3 as the interval between successive probes is 1. There are no more than 20 elements in the data set. Hash function will return an integer from 0 to 19.

Detailed explanation-4: -1 Answer. To explain: Open addressing is the technique which is used for handling collisions in a hash table. Separate chaining is another technique which is used for the same purpose.
