Programming & Computer Science Answers

Two cars A and B leave an intersection at the same time. Car A travels west at an average speed of x

miles per hour and car B travels south at an average speed of y miles per hour. Write a program that

prompts the user to enter the average speed of both the cars and the elapsed time (in seconds) and

outputs the total distance each car has traveled as well as the shortest distance between the cars.

Output data MUST be rounded to 2 decimal places and have precision set so that all data is evenly lined

up. For simplicity, assume that decimal numbers will be no more than 8 digits long.

Below is a nested MPLS network by MTN. With the assumption that Customer 6 (C6) is connected to Router 6 (R6), execute a Dijkstra Algorithm on a Link State routing to determine the shortest path for Customer 6 to transmit packets to every other Customer/Destination connected to the rest of the Routers on the network.

a. Tabulate the executed iteration for the Dijkstra Algorithm using the table below

Rearrange Numbers in String

Given a string, write a program to re-arrange all the numbers appearing in the string in decreasing order. Note: There will not be any negative numbers or numbers with decimal part.

Input

The input will be a single line containing a string.

Output

The output should be a single line containing the modified string with all the numbers in string re-ordered in decreasing order.

Explanation

For example, if the given string is "I am 5 years and 11 months old", the numbers are 5, 11. Your code should print the sentence after re-ordering the numbers as "I am 11 years and 5 months old".

Sample Input 1:

I am 5 years and 11 months old

Sample Output 1:

I am 11 years and 5 months old

Sample Input 2:

I am -5 years and 11.0 old

Sample Output 2:
