Provide the inputs and outputs of each Learning Exercise $($LE$).$

How many Cyclone IV FPGA LEs are required to perform each of the following functions? Show how to configure one or more LEs to perform the function. You should be able to do this by inspection, without performing logic synthesis.

a$.$ the combinational function from Exercise $2\mathrm{.}13($c$)$

b$.$ the combinational function from Exercise $2\mathrm{.}17($c$)$

c$.$ the two$-$output function from Exercise $2\mathrm{.}24$

d$.$ the function from Exercise $2\mathrm{.}35$

e$.$ a four$-$input priority encoder $($see Exercise $2\mathrm{.}36)$
