finish the code: Integers numDonuts and cash are read from input. A donut costs $3$ dollars.

If numDonuts is less than $2,$ output "numDonuts requires at least $2$ to purchase."

If numDonuts is greater than or equal to $2,$ then declare and initialize int variable totalCost with the product of numDonuts and $3.$

If totalCost is less than or equal to cash, output "Approved transaction."

Otherwise, output "Not enough money to buy all."

If cash is greater than or equal to $3,$ output $"$At least one item was purchased."

End with a newline.

Ex: If the input is $1570,$ then the output is:

Approved transaction.

At least one item was purchased. import java.util.Scanner;
