- in c++ Magic Decoder Ring. A one-time pad is a coding device that uses each character of a key string only once to encode and decode a corresponding character in a message string. Thus, the first character in the key is used to encode and decode the first character in the clear message, the second character in the key is used with the second character in the message, etc. No portion of the key is reused in subsequent messages, making for a very solid coding system, assuming a randomly generated key. You will need to create a class titled MagicDecoderRing that contains the variables and functions needed for obtaining the clear and key texts, encoding and decoding the messages, writing out the encoded message etc. You will need to instantiate an instance of this class in your main function to run your program and encode and decode messages.

As soon as a customer enters the line, they are given a token # (serial number). After receiving assistance, the consumer exits the line while the postal worker receives the token back. The employee could inquire as to how many consumers are still unattended at any one time. i) Put the system into practise using a suitable queue data structure, simulating the arrival and departure of consumers at random when the service is finished. ii) If a customer arrives to operate their savings account at the post office, then they are attended to first by permitting them to join a special queue. In such a case, the postal worker attends to them immediately before resuming their normal service of mail delivery.

In the method that is based on the concept of gain, the worst possible situation is assumed: the vehicle leaves the DC with the goods destined for a single customer and, after delivery, the vehicle returns to the DC. Then another customer is inserted in this route. This method is known under the name of: ( ) Clark & Wright ( )Insertion of the furthest point ( ) II - OPT ( ) scan ( )III - OPTA common problem in health informatics is to read a message from another healthcare organization and to parse it to extract the relevant information. In practice, this is a very large problem. However, to get you started thinking in this area, consider receiving a simple message from another organization in the form <<&first name&&last name&&age in years&&medical record number&&diagnosis&>> Your organization needs to read such a message and extract out the five information elements. To do so, it needs to develop a program to accomplish this. Your assignment is to develop pseudocode to accomplish this task. As an example, if the input is: <<&Tom&&Smith&&25&&12345&&pneumonia&>> then you should output the following: First Name: Tom Last Name: Smith Age: 25 Medical Record Number: 12345 Diagnosis: pneumonia
