           if scoreA < 25 and scoreB < 25:

               raise ValueError

           try:

               if abs(scoreA - scoreB) < 2:

                   raise  

               else:

                   break

           except:

               print("difference less than 2")

   

       except ValueError:

           print("Enter correct scores")

#section 3

       print("For Game ", i)

   if scoreA > scoreB:

       team1 = team1 + 1

   else:

       team2 = team2 + 1

#section 4

if team2 > team1:

   print("Team 2 is the winner")

else:

   print("Team 1 is the winner")

Explanation:

There is no way you can run the code without using a break statement because, in a while loop you have to pass an argument that will exit the loop. if you don't your loop will keep running and that's not good.

You might have also gone about it in a way that is a bit complicated. when writing code always look out for ways to make your work easier.

I used a For Loop, While Loop and an array.

#section 1

team1=0  

team2=0  

matches=[1,2,3,4,5]  

for i in matches:  

print("For Game ", i)  

- In this section two variables were declared two variables to hold the final results after both teams have played their 5 games and their scores recorded

- An Array holding the number of games they're to play was also declared. they are playing 5 so the Array "matches" holds 5 elements.

- The first loop here is the "For loop" and what it does is to run the block of code under it for all the elements in the Array.

- finally we print for game "i" where i is each game in the array

#section 2

 while True:

       try:

           scoreA = int(input("Enter score for first team: "))

           scoreB = int(input("Enter score for second team: "))

       

           if scoreA < 25 and scoreB < 25:

               raise ValueError

           try:

               if abs(scoreA - scoreB) < 2:

                   raise  

               else:

                   break

           except:

               print("difference less than 2")

   

       except ValueError:

           print("Enter correct scores")

- A while loop is always true unless it encounters an argument that is not true or a break statement is inserted.

- This section is responsible for taking all the inputs required and if a wrong input is entered it would show the specific error and ask you to make the input again.

- Here the Try and Except is use to handle the errors. When the Try block encounters an error it goes to the Except block and executes whatever it finds there.

- The first try block prompts and takes inputs, it then checks if the values inputted satisfies or violates the 25-point rule.

If it does not satisfy the 25-point rule, it goes to it's error block and prints "enter correct score" and the WHILE loop runs again.

within this Try block is nested another try block. if the first try block does not raise any error it proceeds to the second try block.

- The second Try block checks the difference between the scores and if it is less than 2, it raises an error and prints difference is less than 2 and runs the WHILE loop again.

- If there are no errors it BREAKS out of the WHILE loop then the FOR loop moves to the next match.

#section 3

       print("For Game ", i)

   if scoreA > scoreB:

       team1 = team1 + 1

   else:

       team2 = team2 + 1

- Remember there is still a for loop. This section prints the game we just recorded, and checks which team won. It then adds the win as a point(1) to the teams total score.

#section 4

if team2 > team1:

   print("Team 2 is the winner")

else:

   print("Team 1 is the winner")

- In this section the For Loop has finished running and the final values are ready, it compares the scores of both teams and declares the winner.

I have placed an attachment to help you see the code in action.

The expressionvecCont.empty() empties the vector container of allelements.
Semenov [28]

Answer:

False

Explanation:

vector is like a dynamic array that has a special ability to resize automatically when it required.

vector has several functions:

like, insert() to insert the element in the vector.

delete() for delete the one element at a time.

empty() is also the function used in the vector. It is used for checking the vector is empty or not.

it gives the Boolean value (TRUE or FALSE), if the vector is empty it gives the output TRUE if the vector is not empty it gives the output FALSE.

It is not used for empty or deletes all elements of the vector.

Therefore, the answer is False.

A Turing machine with doubly infinite tape (TMDIT) is similar to an ordinary Turing machine except that its tape is infinite to
umka2103 [35]

Answer and Explanation:

A TM with doubly infinite tape can simulate an ordinary TM. It marks the left-hand end of the input to detect and prevent the head from moving off of that end. To simulate the doubly infinite tape TM by an ordinary TM, we show how to simulate it with a 2-tape TM, which was already shown to be equivalent in power to an ordinary

TM. The first tape of the 2-tape TM is written with the input string, and the second tape is blank. We cut the tape of the doubly infinite tape TM into two parts, at the starting cell of the input string. The portion with the input string and all the blank spaces to its right appears on the first tape of the 2-tape TM. The portion to the left of the input string appears on the second tape, in reverse order.
