Lunh Algorithm is a simple checksum formula use to validate various identification numbers most of famously credit card numbers. Developed by IBM engineer hands Peter lunar, it help detect common data entry errors like single-digit typos or adjacent digit transpositions . The algorithm work by performing a series of arithmetic operations on the digits, which culminates in a sum that must be a multiple of 10 for the number to be considered potentially valid. #lunh #algorithm #maths #mathmatics #c
