There are two tribes on the island of Tufa: the Tu's, who always tell the truth, and the Fa's, who always lie. A traveler encountered three residents of the island, A, B and C, and each made a statement to the traveler: A said "B and C tell the truth if and only if C tells the truth." B said "If A and C tell the truth, then A tells the truth." Csaid "B is lying if and only if A or B is telling the truth." From this information, can you determine which tribes A, B and C belong to? Explain.

Computational Systems

The computation systems can be defined as the systems that are capable of solving a problem that includes calculations either mathematical or logical, and are able to produce the result as an output. For example, a simple calculator that is given a set of numbers and operators as input and produces the result as an output can be defined as a computational system. The above example is a simple illustration only, the computational systems range from simple devices to complex devices such as the systems that control the SpaceX companies, Starlink satellites which are being quite recently seen in the skies at many places globally.
