word_type operator""_w(const char *w, size_t n)¶
Literal for defining word_type over integers less than 10.
This operator provides a convenient brief means of constructing a word_type from an sequence of literal integer digits or a string. For example,
0123_w
produces the same output asword_type({0, 1, 2, ! 3})
.There are some gotchas and this operator should be used with some care: * the parameter \p w must only consist of the integers \f$\{0, \ldots, 9\}\f$. For example, there are no guarantees about the value of `"abc"_w`. * if \p w starts with `0` and is follows by a value greater than `7`, then it is necessary to enclose \p w in quotes. For example, `08_w` will not compile because it is interpreted as an invalid octal. However `"08"_w` behaves as expected. \param w the letters of the word \param n the length of \p w (defaults to the length of \p w) \warning This operator performs no checks on its arguments whatsoever. \returns A value of type \ref word_type. \throws (None) This function guarantees not to throw a `LibsemigroupsException`.
