Given the following input (4322, 1334, 1471, 9679, 1989, 6171, 6173, 4...
Hash function given is mod(10).
9679, 1989 and 4199 all these give same hash value i.e 9
1471 and 6171 give hash value 1

Given the following input (4322, 1334, 1471, 9679, 1989, 6171, 6173, 4...
Hash Function and Hashing:
Hash function is a function that takes in an input (or 'key') and returns a fixed-size value (or 'hash') that represents the input. Hashing is the process of using a hash function to map inputs to their corresponding hashes.
Solution:
The given input is: 4322, 1334, 1471, 9679, 1989, 6171, 6173, 4199
The hash function is: x mod 10
So, the possible hash values are: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
Let's apply the hash function to each input:
● 4322 mod 10 = 2
● 1334 mod 10 = 4
● 1471 mod 10 = 1
● 9679 mod 10 = 9
● 1989 mod 10 = 9
● 6171 mod 10 = 1
● 6173 mod 10 = 3
● 4199 mod 10 = 9
Now, let's check each statement:
i. 9679, 1989, 4199 hash to the same value
Yes, they all hash to 9. So, this statement is true.
ii. 1471, 6171 has to the same value
Yes, they both hash to 1. So, this statement is also true.
iii. All elements hash to the same value
No, this is not true. The elements hash to different values.
iv. Each element hashes to a different value
No, this is also not true. Some elements hash to the same value.
Therefore, the correct answer is option 'C': i and ii only.
