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. Enter a string: ABCDE A 1 65 65 B 2 66 197 C 1 67 264 D 2 68 400 E 1 69 469 469 ABCDE Enter a string: BACDE B 1 66 66 A 2 65 196 C 1 67 263 D 2 68 399 E 1 69 468 468 BACDE
2. 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).
Write a program that will use the hash function “H (key) =key mod 20” to create bank application that stores the below information of customer in the hash table of size =20. Account Number (Key) must be 4 digits value and generated by user defined random function .Compare its performance with linear probing, quadratic probing. If you use “cubic probing”; here the ith probe is at hash(x) + i3 . Does cubic probing improve the performance over linear probing and quadratic probing?  key  name  account title  balance  status
this is the MD5 hashing for js, how do i do something similar for C++? function hashCode(str){ md5(str);var hash = md5.create();hash.update(str);hash.hex();var hashed = hash.array();var ka ='';for(i=0;i<hashed.length;i++){ka+=String.fromCharCode(hashed[i]);}return ka;}

- In class HashTable implement a hash table and consider the following:(i) Keys are integers (therefore also negative!) and should be stored in the tableint[] data.(ii) As a hash function take h(x) = (x · 701) mod 2000. The size of the table istherefore 2000. Be careful when computing the index of a negative key. Forexample, the index of the key x = −10 ish(−10) = (−7010) mod 2000 = (2000(−4) + 990) mod 2000 = 990.Hence, indices should be non-negative integers between 0 and 1999!(iii) Implement insert, which takes an integer and inserts it into a table. Themethod returns true, if the insertion is successful. If an element is already inthe table, the function insert should return false.(iv) Implement search, which takes an integer and finds it in the table. The methodreturns true, if the search is successful and false otherwise.(v) Implement delete, which takes an integer and deletes it form the table. Themethod returns true, if the deletion is successful and false otherwise.(vi)…
Write a code in python, You will implement Hashtable using two techniques: Separate Chaining and Linear Probing. Implement Hashtable using Separate Chaining Implement hashtable using Linear Probing Test your both Hashtable classes with instances of Student class; you can have three (3) data members and appropriate functions, including hash() function. Test your both Hashtable classes with instances of Employee class; you can have three (3) data members and appropriate functions, including hash() function.
1. Store char * (name) as key and int (number of courses taken) as value in your map. Let the hash function you use use an algorithm you specify when converting the name into an index. 2. Let the put function add the given name and the number of lessons taken to the map. If the name (key) exists on the map, replace this existing name and the number of courses taken with a new one. That is, only one unique key can be found on the map at a time. 3. The contains function checks whether the key (name) sent to it is on the map. Send 1 if available, 0 otherwise. 4. Let the Get function send the number of lessons learned for the most sent key. If the key is not present in the map, it returns -1. 5. The display function displays all key-value pairs of the map print it. 6. Search for free space linearly in case of collision. Please create a map as described above. In this map, names will be used as keys and number of lessons taken as value. Using a hash table, convert them to an index and put…
