You are required to design a digital circuit for a cookie vending machine. Themachine sells cookies for $0\mathrm{.}75$ JD each. Assume that there are only $0\mathrm{.}25,0\mathrm{.}50,$ and$1$ JD coins. Three switches on the board can denote three different types of coins.With the total number of input coins, two LEDs $($Green$)$ should display the numberof cookies a user can buy $($max$.$ two cookies$).$ Whenever there is a change aftergetting the cookie, the machine will turn on another LED $($RED$)$ to remind the usersof changes. For example, if one $0\mathrm{.}25$ and one JD coin are inserted in the slot, turn onone of the Green LEDs $($to indicate the number of cookies$)$ and the RED LED tosignal the change. However, if one $0\mathrm{.}50$ or one $0\mathrm{.}25$ is inserted in the slot, do notturn on the LED. That is no cookie, no change. Design and build the logic circuitand show all the steps.
