ISRO | ISRO CS 2016 | Question 26

A Hash Function f is defined as f(key) = key mod 7. With linear probing, while inserting the keys 37, 38, 72, 48, 98, 11, 56 into a table indexed from 0, in which location the key 11 will be stored (Count table index 0 as 0^thlocation)?
(A) 3
(B) 4
(C) 5
(D) 6


Answer: (C)

Explanation: Hash function = f(key) = key mod 7
insertion order= 37, 38, 72, 48, 98, 11, 56
Insert 37: 37 mod 7 = 2
Insert 38: 38 mod 7 = 3
Insert 72: 72 mod 7 = 2, but already occupied, so after linear probing it would occupy index 4.
Insert 48: 48 mod 7 = 6
Insert 98: 98 mod 7 = 0
Insert 11: 11 mod 7 = 4, but already occupied, after linear probing it would get into index 5.
So, option (C) is correct.
