    An array of integer numbers is taken as input and sorted.Number Sequence generates a string that represents sequences of contiguous numbers as ranges with the first and the last sequence number separated by dashes. Non contiguous numbers are separated commas.For instance, array(1,2,3,5,7,8,9) is transformed in the sequence "1-3, 5, 7-9"Requirements: PHP 5.0 or higher

    The syntax used to write the formulas can be defined. Basic logic operations (and, or, not, implies, etc...) can be applied. Proposition (cleaning, developing, disjunctive form, conjunctive form) can be transformed.You can even make demonstrations of your proposition, by looking up the values table or simply by demonstrating it (simple analysis of the disjunctive form: not too greedy). The FOLP ...
