    BioR is a simple script for calculating a personal biorhythm values given the birth date and the date of a given day of life. The (most common) theory of biorhythm states that our daily lives are significantly affected by simple rhythmic cycles.When we are born, three cycles begin from zero point and then oscillate between -100 and 100 till we ...

    Permutation to permutate a string (short one) to return subsets with variable parameters. "ABC" returns a,b,c,aa,ab,ac,ba,bb,,aca,acb ... Initially implemented with a recursive solution there was the bothersome stack overflow and also other minor problems... later when implemented with a tripple for loop it still fails the volume test though try not to have too many characters or it will exceed ...
