Textbook Question

Chapter 8, Problem 6PP

Write a program that reads in a line of text and outputs the line with all the digits in all integer numbers replaced with ‘x’. For example,

Input:

My userID is john17 and my 4 digit pin is 1234 which is secret.

Output:

My userID is john17 and my x digit pin is xxxx which is secret.

Note that if a digit is part of a word, then the digit is not changed to an ‘x’. For example, note that john17 is NOT changed to johnxx. Include a loop that allows the user to repeat this calculation again until the user says she or he wants to end the program.

Dijkstra's Algorithm (part 1). Consider the network shown below, and Dijkstra’s link-state algorithm. Here, we are interested in computing the least cost path from node E (note: the start node here is E) to all other nodes using Dijkstra's algorithm. Using the algorithm statement used in the textbook and its visual representation, complete the "Step 0" row in the table below showing the link state algorithm’s execution by matching the table entries (i), (ii), (iii), and (iv) with their values. Write down your final [correct] answer, as you‘ll need it for the next question.
