The implementation methods are as follows: Copy Code code as follows: Package Main Import ( "FMT" "Strings" ) Const INPUT = ' 49927398716 499273

The verification of the credit card number is based on the Luhn algorithm: the old IBM engineer Hans Peter Luhn invented in 1954.The patent was applied at that time and is now open to the public domain of knowledge as a standard for international standards organizations: ISO

According to the algorithm of the payment card check digit in ISO 2894 the Luhn Mod-10 method stipulates: 1. Multiply each digit on the card number by the weight. The rule is that if the number of card number is even, then the first bit is multiplied by 2, otherwise it is m

Luhn algorithm 1. Starting with the last digit of the card number, the inverse adds the odd digits (1, 3, 5, and so on). 2, starting from the last digit of the card number, the inverse of the even digit number, first multiplied by 2 (if the product is two digits, then subtract 9), and then sum. 3, the sum of odd digi
