Part I Assume that a N x M matrix is stored in a file. However, the file is corrupted somehow, and some numbers replaced with asterisk symbol (*). Write a method that reads given corrupted file and fills the missing data with the average of the column. For example, given matrix 1 2 3 4 7 8 10 11 12, missing data should be replaced with 2+8+11 = 7. Part II Assume that multiple messages are encrypted with Ceaser ciphering' and stored in a file. Write a method that deciphers the messages with given shift value. Note: Use English alphabet with only lower-case characters. Part III Assume that multiple arithmetic operations² are stored in a file. However, some of the results are wrong. Write a method that finds the operations which the results are wrong in given file. For example, given operations 1.0 + 2.0 4.0 %3D 2.5 + 2.5 5.0 3.0 / 2.0 1.0 %3D the method should return Oth and 2nd line strings. Note: Do not round the numbers in any step of the calculation.

Javascript: A startup that builds a chat app wants to identify highly social users. All the chat data is in a large log file with three values on each line - the sender ID, receipient ID, and the number of messages. Given a threshold number, find the number of users that appear at least as many times as this threshold.For example:USERA USERB 14USERA USERC 94USERB USERB 3...Note: On the third line, a user sents a message to himself.Inputslogs = a list of lines where each line is a stringthreshold = a numberOutputReturn a list of sorted user IDs. If the same user appears in the same line, only count them once.
Write a program that randomly fills in 0s and 1s into a 4-by-4 matrix, prints the matrix, and finds the first row and column with the most 1s. Here is a sample run of the program: 0011 0011 1101 1011 The largest row index: 2 The largest column index: 3
Write a method that sums all the numbers in the major diagonal in an nxn matrix of double values using the following header: public static double sumMajorDiagonal(double[][] m) Write a test program that first prompts the user to enter the dimension n of an nxn matrix, then asks them to enter the matrix row by row (with the elements separated by spaces). The program should then print out the sum of the major diagonal of the matrix.

In Java language
Implement a city database using ordered lists. Each database record contains the name of the city (a string of arbitrary length) and the coordinates of the city expressed as integer x and y coordinates. Your database should allow records to be inserted, deleted by name, and searched by name. Another operation that should be supported is to print all records within a given distance of a specified point/coordinate. The order of cities should be alphabetically by city name. Implement the database using: an array- based list implementation. By using JAVA.
All of these statements are related to hash function, hash table.

In this exercise you will design and implement a simple encryption program that can either encrypt or decrypt a string of text by following the steps below. Create a dictionary dict that maps each (lower case) character of the basic Latin alphabet to another. Make sure no one letter is mapped to itself. Do not use a simple ordering, such as reversing the alphabet. This will act as your cipher. Your program should be able to ask user for a text and encrypt it. Your program will take each character in the string and swap it with the corresponding character from the cipher, print the encrypted text. Your program should be able to decrypt encrypted text as well. It should perform the opposite operation as the encrypt does. Print the decrypted text. Create a loop that asks if the user would like to encrypt some text, decrypt some cipher text, or exit the program. Perform the operation the user selects, printing the computed text if applicable.
