- Find 2N strings, each of length 2N, that have the same hashCode() value, supposing that the hashCode() implementation for String is the following:public int hashCode(){ int hash = 0; for (int i = 0; i < length(); i ++) hash = (hash * 31) + charAt(i); return hash;}Strong hint : Aa and BB have the same value2. Implement the hash table for the following elements: a. 22,32,45,67,89,9 Use Double hashing technique to handle the collision. [ hash1(key)=key%10, hash2(key)=PRIME- (key%PRIME) ].Extendible hash index:Consider the Extendible Hashing index shown in figure below: Show the state of the index after each operation:a) Insertion of entry 1b) Insertion of entry 23c) Deletion of entry 30
- write a simple hashing function that uses addition and multiplication and then find a pair of strings that will return the same hash value for different strings (i.e you will cause a Hash Collision). The algorithm uses multiplication based on the position of a letter in the hash to avoid a hash collision when two letters are transposed like in 'ABCDE' and 'ABDCE'. Your strings need to be at least three characters long and no more than 10 characters long. Here is the code that computes your hash: while True: txt = input("Enter a string: ") if len(txt) < 1 : break hv = 0 pos = 0 for let in txt: pos = ( pos % 2 ) + 1 hv = (hv + (pos * ord(let))) % 1000000 print(let, pos, ord(let), hv) print(hv, txt) For simplicity we will only use upper and lower case ASCII letters in our text strings.

- With hashing, as the load factor increases, the chance of collisions decreases. State whether the statement is true or false. If false, explain why.We have the hashTable H with bucketsize=10 and hash function N%10. If we iterate over all the keys and print their values after this piece of code, what would be the first value shown in the console:* 15 22 31 402. Write a program by implementing your own PRNG (e.g., using a hash function). You must not use any existing random class or function but implement your own. Produce random bytes (like above). Note the purpose of this part is not to design a strong PRNG that passes randomness tests, but rather for comparison with an existing strong PRNG (above).
