Prompt the user and read in the number of the opponent team. It is probably helpful to think of the first team as the home team for this game, and the second team as the away team. 3. Prompt the user and read in a team’s score for the current game. Use the team’s number when asking for the score in your printf statement. 4. Prompt the user and read in the opponent’s score for that game. Again, use the opponent’s team number when asking for the score. 5. Notify the user and repeat steps 3 and 4 in the case that the user enters a negative value. 6. Calculate the points earned by each team and add it to a cumulative score. A win is worth 3 points, a draw is worth 1 point and a loss is zero points. Also update the amount of games played by each team and their goals for and against. 7.

- A cashier distributes change using the maximum number of five dollar bills, followed by one dollar bills. For example, 19 yields 3 fives and 4 ones. Write a single statement that assigns the number of 1 dollar bills to variable numOnes, given amountToChange. Hint: Use the % operator. C++A half-life is the amount of time it takes for a substance or entity to fall to half its original value. Caffeine has a half-life of about 6 hours in humans. Given caffeine amount (in mg) as input, output the caffeine level after 6, 12, and 24 hours. Use a string formatting expression with conversion specifiers to output the caffeine amount as floating-point numbers. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print(f'{your_value:.2f}') In python.This Code print the first occurrences of x, Please Modify the code to print the last occurrences of x and print how many times it exists? ( with explanation for each line if possible) many thanks.
