Fix a finite alphabet
WebAlphabet is defined as a non empty finite set or nonempty set of symbols. The members of alphabet are the symbols of the alphabet. We use capital Greek letter Σ to designate the alphabets and Γ (pronounced as gamma) to designate the typewriter font for symbols. Examples: Σ 1 = {0, 1} Σ 2 = {a, b, …, z}, the set of all lower case letters Web1. a determination of the place where something is 2. an exemption granted after influence (e.g., money) is brought to bear 3. the act of putting something in …
