Consider the following schema:

Suppliers $($sid$,$ sName, address$)$

Parts $($pid$,$ pName, carModel$)$

Supplier$\_$parts $($sid$,$ pid, cost$)$

Using Relational Algebra...

$1)$ Find the name of suppliers who supply parts for both Toyota and Ford. Keep in mind that a supplier who only sells parts for Ford but not Toyota would not be in the result. Rename sName to Supplier name when displaying the results.

$2)$ Display the name of suppliers who supply parts for only Toyota or only Ford. Keep in mind that a supplier that supplies parts for both Toyota and Ford would not be in the result

$3)$ Display the address of the suppliers who supply parts for only Ford, who sell Bumpers that are more than $$100.$
