Using a second hash function to compute increments for probe increments is called
a. probe counting
b. sequence hashing
c. double hashing
d. function hashing

(C) Double Hashing.

Explanation:

Double hashing is technique to counter collision in hashmaps specially in open Addressed hashmaps.

Collision occurs when we are inserting a key in a hashmap that is already present in the hashmap.Now we have two same keys with different values.

Double hashing uses a second hash function when there is collision.

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
