Rules of Inference and Methods of Proof
... Solution. We can show that this statement is false by using a counterexample: the number 3 can not be written as a sequence of two integers. We leave to the reader to check this fact. 8-Uniqueness Proof : a proof that there is exactly one element satisfying a specified property. To do so, two steps ...

... When using an integer representation of a truth table, the output value of the LUT can be obtained by calculating a bit index k based on the input values of the LUT, in which case the LUT's output value is the kth bit of the integer. For example, to evaluate the output value of a LUT given an array ...
