Write the following functions in C whose signatures are provided below:

Restrictions:

No relational operators like =, , or pow() allowed, nor can there be special cases on bitwidth, as such no if switch ?: is allowed for special bitwidths, but LOGICAL operators/ conidtional statements are allowed especially to sort out over/underflow cases, == and != ARE ALLOWED as well.

An example:

The function allows two operands (or more) to be added together and if their values exceed the min/max for the provided bitwidth, the answer saturates at the respective min/max. Note 126+5 > 127, but it saturated at the maximum.

long signed_min(int bitwidth); long signed max(int bitwidth): long sat_add (long operand1, long operand2, int bitwidth)
