Assuming a message “Exams!” is to be transmitted over a network. If the message is made up of strings with the given probability: e = 0.4, x = 0.1, a = 0.2, m = 0.1, s = 0.1, and ! = 0.1, derive:

a. The codeword using Arithmetic coding procedures

b. The original message by decoding the codeword in (a).

program to convert 6 digits numbers into words

A program is required for a computer game. The user keys in the number of rounds he wishes to play.

For each round the user enters his lucky number. The program takes the number and divides it with a

secret number. If the remainder of the division is zero, it is considered a draw for the round and the total

score is incriminated by 1. Otherwise if it is any other even number, it is considered a win for the round

and the total score is incremented by 3. However if it is an odd number, it is considered a loss for the

round and the total score is decremented by 3. This is done until he completes his rounds. He wins if the

total score at the end is a positive number. Write a Java program to accomplish this.

Consider a mx n matrix inmatrix of string elements containing alphanumeric values, where m>1, n >=1. Identify and print outarr based on the logic below:

• Traverse the inmatrix in clockwise spiral way starting from the element at (0,0) •

traversal until one of the two conditions is met • The element or the concatenated string is a palindrome with length greater

than 1 There are no more elements left for traversal

. Add the concatenated string to outarr

. If there is any element which has not yet been visited in the traversal, repeat the two steps, forming a new concatenated string that starts with the next element present after the last element previously traversed

Note: Perform case-sensitive comparison

Input format:

First line will contain number of rows m of inmatrix

The next m lines will contain the elements of inmatrix. Each line will have n string

elements separated by (comma)

Create a program that reads trom the console two integer numbers (int) and prints now many numbers between them exists, such that remainder of their division by 5 is O. E

write a JS program to

• filter the candidates who have scored more than 75 points in every even

input

• the input will be single line containing an array of objects candidatesList

output

• the output should be single line containing an array with names of the selected candidates.

input1

[{'name': 'Blake Hodges', 'points':[76, 98, 88, 84]}

output1

['Blake Hodges]

Develop a swing application for login validation of a system as shown in the figure. The

application shows two options: one Sign up and another Sign in. When Sign up is selected, a

new screen will appear for asking name, username, password. If the entered username and

password do not exist in the database, it will show a successful message [Name] has

successfully registered and store corresponding username, password in the database,

otherwise the message [Name] already exists in the system will be displayed. On the other

hand, when Sign In option is selected, the user will be prompted to enter username,

password as shown in the figure. Eventually, the application checks whether username and

password both match with some entry in the database. If such entry found in the database,

then a welcome message Welcome [Name] will appear, otherwise an unsuccessful login

message Wrong username/password will be displayed. For message display, the swing dialogs can be used.
