Given a string S containing only digits, Your task is to complete the function genIp() which returns a vector containing all possible combinations of valid IPv4 IP addresses and takes only a string S as its only argument. Note: Order doesn't matter. For string 11211 the IP address possible are 1.1.2.11 1.1.21.1 1.12.1.1 11.2.1.1

Write a program to Validate an IPv4 Address. According to Wikipedia, IPv4 addresses are canonically represented in dot-decimal notation, which consists of four decimal numbers, each ranging from 0 to 255, separated by dots, e.g., 172.16.254.1 . The generalized form of an IPv4 address is (0-255).(0-255).(0-255).(0-255). Here we are considering numbers only from 0 to 255 and any additional leading zeroes will be considered invalid. Your task is to complete the function isValid which returns 1, if the ip address is valid else returns 0. The function takes a string s as its only argument . **************************************************************************/ // SOLUTION (in C++): #include <bits/stdc++.h> using namespace std; int isValid(string s) { s += '.'; int countDots = 0; string str = ""; for (int i = 0; i < s.length(); i++) {…
Defanging an IP Address • Given a valid (IPv4) IP address, a defanged IP address replaces every period “.” with “[.]”. • Example: address = “255.100.50.0”, defanged = “255[.]100[.]50[.]0” • Write a function that accepts a string as input (valid IP address) and returns the defanged IP address. • Test the function in the main method. Sample output at the bottom. • Have the expected defanged address hardcoded and compare it to result from the function
Suppose you generate the following RSA key pairs:• p = 37199• q = 49031• N = p · q = 1823904169• (p − 1) · (q − 1) = 1823817940• e = 65537 (for encryption)• d = 1578812933 (for decrption)Assuming a=01, b=02, . . . , z=26, and we group the digits in groups of three. (ii) If you receive strings of digits from a sender: 199770170, 1288754980, 324346846, 1370682962, decrypt the message.
Write a program Minesweeper.java that takes three integer command-line arguments m, n, and k and prints an m-by-n grid of cells with k mines, using asterisks for mines and integers for the neighboring mine counts (with two space characters between each cell). To do so, Generate an m-by-n grid of cells, with exactly k of the mn cells containing mines, uniformly at random. For each cell not containing a mine, count the number of neighboring mines (above, below, left, right, or diagonal)

(i) If someone wants to send the following message: “SELLALL” using your public key, what strings of digits should they send you (i.e., encrypt this message)?
Implement a class RLE that uses fixed-length encoding, to compress ASCII bytestreams using relatively few different characters, includingthe code as part of the encoded bitstream. Add code to compress() to make a stringalpha with all the distinct characters in the message and use it to make an Alphabet foruse in compress(), prepend alpha (8-bit encoding plus its length) to the compressedbitstream, then add code to expand() to read the alphabet before expansion.
My final question on the day seems to be on properly slicing strings. Currently I have URL = input("Please enter the absolute URL: ")if URL.startswith("https"): print("Type: https")elif URL.startswith("http"): print("http") however I get stuck when trying to slice out the domain and path and the book is only showing simpler commands (startswith, endswith, find, count etc..), so I am unfamiliar with something more complex like URLParse which I saw elsewhere.
Suppose you’re consulting for a bank that’s concerned about fraud detection, and they come to youwith the following problem. They have a collection of n bank cards that they’ve confiscated, suspectingthem of being used in fraud. Each bank card is a small plastic object, containing a magnetic stripe withsome encrypted data, and it corresponds to a unique account in the bank. Each account can have manybank cards corresponding to it, and we’ll say that two bank cards are equivalent if they correspond to thesame account.It’s very difficult to read the account number off a bank card directly, but the bank has a high-tech “equivalence tester” that takes two bank cards and, after performing some computations, determines whether theyare equivalent.Their question is the following: among the collection of n cards, is there a set of more than n/2 of themthat are all equivalent to one another? Assume that the only feasible operations you can do with the cardsare to pick two of them and plug them…
Consider the paths in the image below. There are many paths through this network – which one is the longest?
In a special case of a permutation cipher, we take a message, M, and write its letters in an s× t table, in a row-major fashion, and then let the ciphertext be a column-major listing of the entries in the table. For example, to encrypt the message ATTACKATDAWN, using a 3 × 4 table, we would write the message as ATTA CKAT DAWN and then write down the ciphertext as ACDTKATAWATN. The secret key in this cryptosystem is the pair (s, t). How is decryption done in this cryptosystem? Also, how hard would it be to attack this cryptosystem using a ciphertext-only attack?
When Bob wants to send Alice a message M on the Internet, he breaks M into n data packets, numbers the packets consecutively, and injects them into the network. When the packets arrive at Alice’s computer, they may be out of order, so Alice must assemble the sequence of n packets in order before she can be sure she has the entire message. Describe an efficient scheme for Alice to do this. What is the running time of this algorithm? From Data Structures and Algorithms C-7.56
You are given a string X of length n and another string Y of length m ≤n. Say,the indexes p1, p2, p3, p4 and q1, q2, q3, q4 form two sub-sequences, i.e., 0 ≤ p1 < p2 < p3 < p4 < nand 0 ≤q1 < q2 < q3 < q4 < n; then, they are non-overlapping if p4 < q1.The task is to count the maximum number of non-overlapping sub-sequences of X that are thesame as Y . Thus, if X = GAXTYAWBGTAUGBTABGRGTAXB and Y = GTAB, then the answer is3 as shown by the red fonts. We cannot select the underlined GTAB as it overlaps with a red GTAB(i.e., among overlapping sub-sequences, you can select only one of them).Describe an O(m + n) time algorithm to obtain the count. Write a pseudo-code.
