Enter a string through the keyboard

For end press Ctrl+A

Enter an integer number through the keyboard

Create an undirected graph whose vertices will have the values of the characters of the string, and the edges will be randomly generated, with the highest value of any edge being the value entered through the keyboard

Create two queues, one that will receive integer values, and the other one characters

In the first one enter the values of the edges in the graph sorted in descending order In the second one enter the vertices among which are those edges, each separated by a comma and a space

Print the two queues
