The instance variable population could be returned instead of p, which is local to the constructor.
What is a constructor?A constructor, in object-oriented programming, is a special method of a class or structure that initializes a newly created object of that type. A constructor call is made automatically each time an object is created.
Similar to an instance method, a constructor can be used to set an object's members to default or user-defined values. It typically has the same name as the class.
Since a constructor lacks a return type, despite looking similar, it is not a valid method. The constructor initializes the object, not running code to perform a task, and it is not allowed to be static, final, abstract, or synchronized.

true or false? in a known-plaintext attack (kpa), the cryptanalyst hs access only to a segment of encrpted data and has no choice as to what that data might be
Yes , it’s true. In a known-plaintext attack (kpa), the cryptanalyst can only view a small portion of encrypted data, and he or she has no control over what that data might be.
The attacker also has access to one or more pairs of plaintext/ciphertext in a Known Plaintext Attack (KPA). Specifically, consider the scenario where key and plaintext were used to derive the ciphertext (either of which the attacker is trying to find). The attacker is also aware of what are the locations of the output from key encrypting. That is, the assailant is aware of a pair. They might be familiar with further pairings (obtained with the same key).
A straightforward illustration would be if the unencrypted messages had a set expiration date after which they would become publicly available. such as the location of a planned public event. The coordinates are encrypted and kept secret prior to the event. But when the incident occurs, the attacker has discovered the value of the coordinates /plaintext while the coordinates were decrypted (without knowing the key).
In general, a cipher is easier to break the more plaintext/ciphertext pairs that are known.

Good Subsequences A subsequence of a given string is generated by deleting zero or more characters from a string, then concatenating the remaining characters. A good subsequence is one where the frequency of each character is the same. Given a string that consists ofnLatin letters, determine how many good subsequences it contains. Since the answer can be quite large, compute its modulo(10 9+7)Note: An empty subsequence is not a good subsequence. Example word = "abca" A total of 15 non-empty subsequences can be formed from words.

you want to connect your small company network to the internet. your isp provides you with a single ip address that is to be shared between all hosts on your private network. you do not want external hosts to be able to initiate connections to internal hosts. what type of network address translation (nat) should you implement?
For the purpose of sharing public addresses among numerous private hosts, use Dynamic Network Address Translation (NAT).
Dynamic NAT permits private hosts to connect to the internet but forbids public hosts from initiating connections with private hosts.
A large number of hosts with private IP addresses can share an equal or smaller number of public IP addresses in a dynamic NAT.To link a port number to a request from a private host, the NAT router employs Port Address Translation (PAT).
Although it may appear to be very similar to a Dynamic PAT, the main distinction is that this is a NAT—only the IP address is changing. This means that a single public IP address cannot be used simultaneously by several internal Hosts.
It should be noted that individuals frequently use the phrase "dynamic NAT" when talking about address translation when they really mean "dynamic PAT." Dynamic NAT is rarely utilised in production for the reasons stated above. It is a dynamic PAT if a single IP address is used by numerous internal users and if the port number changes.

write a method contains() that returns true if the key is stored in the array values. the key is stored using closed hashing with linear probing method and uses keytoindex() as the hash function. (keytoindex() is already defined and provided for you). linear probing means that when we have a collision, we check the next (hence linear) position to see if the key is there (probing). we continue until we find they key or find an empty slot (null) in values. The details of the algorithm are:
Compute the index for the key by calling keyToIndex().
If position index in values is empty (i.e. null) then the key is not found and we return false.
If position index is in use (i.e., not null) then we compare the key with the value stored at index. If they are the same, then the key exists and we return true.
Otherwise, the position index is in use and the key stored there is not the same as the key being searched. This is a collision and we must resolve it using linear probing. Increment the index returned by keyToIndex() by one and check the next position. Continue doing this until either you find a position with the key already stored (return true) or you find an empty position (return false). When you increment index, make sure you wrap it around the end of the values table using the remainder (modulo) so that you check all possible positions.
boolean contains(String key, String values[])
{
int index = keyToIndex(key);

Boolean includes (String key, String values[]) <your code here>: int index = keyToIndex(key);.
A technique called hashing is used to distinguish one particular object from a collection of related ones. Let's say a key is given to an item to make searching easier. One can use a straightforward array akin to a data structure to store the key/value combination, where keys (integers) can be used directly as an index to store values.
Hashing should be employed, nevertheless, when the keys are big and cannot be utilized as an index directly. During hashing, hash functions are used to break up huge keys into smaller ones. The values are then kept in a hash table, a type of data structure. Using linear probing the hashing method might be used to produce an array index that has already been used. If this is the case, we can look into each subsequent cell in the array until we discover one that is empty. This method is known as linear probing.
