An alphabet is a finite set of letters In the case of Spanish

But before I go into more detail about this last approach, let me address some fundamental issues using the ensemble approach. Please keep in mind that we are doing this because we want to describe how to build proprietary special purpose languages ​​to increase the productivity and quality of our software development (and testing) processes.

Definitions
that set has 30 letters (counting ch, ll and ü), with which we can construct “correct” words, sentences and texts in that language, but also phrases that are not considered part of it (such as “añu is morgen”). We can say then that Spanish is a set of phrases considered “correct”, which in turn is a subset of all the phrases that can be written with its alphabet.

Let's generalize a bit and define the alphabet taiwan consumer email list a finite set containing n characters. We will say that it has a cardinality of n , and we will write it |B| = n .

Certainly, B* is an infinite set, but one that we call “countable”, since we can use the natural numbers IN (IN = {0, 1, 2, …}) to list all its elements in order: for i = 0 (a natural number) we know that there is 1 string (another natural number), for i = 1 we know that there are n strings, for i = 2 there are n 2 , and so on. This allows us to say that the cardinality of B* is the same as that of IN. In other words: given the finite alphabet B, we can build as many strings with its characters as there are natural numbers.

The above is true regardless of the number of elements in B. If B were the largest extension of the ASCII code, this implies that the number of character strings that we can write on a computer (or any device for processing information) is infinite, but it is countable.

Finally: given the set A, ɚ(A) (“the power set of the set A”) denotes the set consisting of the subsets of A. Some examples:
