Q-2: Suppose you are given the following set of keys to insert into a hash table that holds exactly 11 values: 113, 117, 97, 100, 114, 108, 116, 105, 99 Which of the following best demonstrates the contents of the hash table after all the keys have been inserted using linear probing? A Hash is a dictionary-like collection of unique keys and their values. Also called associative arrays, they are similar to Arrays, but where an Array uses integers as its index, a Hash allows you to use any object type. Hashes enumerate their values in the order that the corresponding keys. The RSA problem is defined as the task of taking eth roots modulo a composite n: recovering a value m such that c ≡ m e (mod n), where (n, e) is an RSA public key and c is an RSA ciphertext. Currently the most promising approach to solving the RSA problem is to factor the modulus n. Hash Functions and Hash Tables. A hash function h maps keys of a given type to integers in a fixed interval 0;:::;N -1. We call h(x) hash value of x. Examples: I h(x) = x mod N is a hash function for integer keys.

Hashing is a method of turning some kind of data into a relatively smallnumber that may serve as a digital 'fingerprint' of the data. Thehashing algorithm manipulates the data to create such fingerprints, called hashvalues.These hash values are usually used as indices into hash tables. Remember thatindexing into an array only takes O(1) time, thus if we could have a fasthashing algorithm to generate the index corresponding to the data (keys +values), then we could achieve constant time for the basic operations in a map.The array itself is called a hash table. For example, the 911 emergencysystem can take your phone number, convert it to a suitable integer i,and store a reference to your street address in the array element A[i].We say that the telephone number (the search key) maps or hashes to the index i.
Generate new SSH keysTo generate new SSH keys enter the following command: ssh-keygenUpon entering this command, you'll be asked where to save the key. This is extra security which will make the key unusable without your passphrase, so if someone else copied your key, they could not impersonate you to gain access.
and make new keys). To do this you need to generate an SSH key: Check for existing SSH keysFirst, check whether there are already keys on the computer you are using to connect to the Raspberry Pi: ls /.sshIf you see files named idrsa.pub or iddsa.pub you have keys set up already, so you can skip the generating keys step (or delete these files with rm id. We suggest you save it in the default location ( /home/pi/.ssh/idrsa) by just hitting Enter.You'll also be asked to enter a passphrase.
In general, ahash table consists of two major components, a bucket array and a hashfunction, where a bucket array is used to store the data (key-value entries) according to their computed indices and a hash function h maps keys of a given type to integers in a fixedinterval [0, N-1]. For example: h(x) = x mod N is a hash function for integer keys and the integer h(x) is called the hash value of key x.

Hash functions are designed to be fast and to yield few hash collisions inexpected input domains. Collisions are inevitable, however. In hash tables, collisions inhibit the distinguishing ofdata, making records more costly to find. Does wep generate a new dynamic key. As we will see, the worst-case runningtime of map operations in an n-entry hash table is O(n), a hashtable can usually perform these operations in O(1) expected time.
