This homework is due ?? March, 4:30 PM.

Copies of `espress` are also available on `bulldog.unca.edu`
and the UNCA CSCI workstations.

Use the software tool `espresso` to minimize the circuits described
in this homework.
For each problem, you need to hand in a printout showing the input file
and the `espresso` output.
The printout should also have the output annotated
to show the minimized function in algebraic form.

Minimize the following functions.

- f(
`a`,`b`,`c`,`d`) = Σ(0,1,4,5,12,13) - f(
`a`,`b`,`c`,`d`,`e`) = Σ(0,4,18,19,22,23,25,29) - f(
`v`,`w`,`x`,`y`,`z`) = Σ(2,8,9,10,13,15,16,18,19,23) + d(3,11,17,22) - f(
`x`,`y`,`z`) =`y``z`' +`x`'`y``z`+`x``y``z` - f(
`w`,`x`,`y`,`z`) =`x`+`x``y``z`+`x`'`y``z`+`x`'`y`+`w``x`+`w`'`x`

Minimize the following triple of functions simultaneously, that is,
with one `espresso` input file.

- f(
`w`,`x`,`y`,`z`) = Σ(1,7,11,13) + d(0,5,10,15) - g(
`w`,`x`,`y`,`z`) = Σ(1,7,8,12,14,15) + d(2,4,6,10) - h(
`w`,`x`,`y`,`z`) = Σ(0,4,12,15) + d(3,6)
