Without using any other library functions or operators, show how the meaning of the following

pattern matching definitions for logical conjunction && can be expressed using conditional if$/$else

expressions.

$($a$)(10$ points$).$

True && True $=$ True

$\_$ &&$\_,=$ False

Hint: use two nested conditional expressions.

$($b$)(10$ points$).$

True && $b=b$

False && $\_=$ False
