$4\mathrm{.}1$ Bit Manipulations

Table $1$ describes a set of functions that manipulate and test sets of bits. The "Rating" field

gives the difficulty rating $($the number of points$)$ for the puzzle, and the "Max Ops" field gives the

maximum number of operators you are allowed to use to implement each function. See the

comments in bits.c for more details on the desired behavior of the functions. You may also refer

to the test functions in tests.c$.$ These are used as reference functions to express the correct

behavior of your functions, although they don't satisfy the coding rules for your functions.
