design and construct a circuit for a cookie vending machine. The machine sells cookie for 75 Yen each. Assume that there are only 25, 50, and 100 Yen coins. Three different types of coins can be denoted by three different switches on the board, respectively. With the total amount of input coins, seven-segment display A should display the number of cookies that a user can buy. Whenever there is change after getting the cookie? the machine will turn on an LED to remind the users for changes. For example, if one 25 and one 100 Yen coins are inserted in the slot, turn on the LED to signal the change. However, if one 50 or one 25 are inserted in the slot, don't turn on the LED. That is no cookie no change.
