A statistical approach to this problem will be outlined and the various steps of a system based on this approach will be described. Since this process varies among individuals and since similar ideas are therefore relayed at different levels of specificity and by means of different words, the problem of literature searching by machines still presents major difficulties. Written communication of ideas is carried out on the basis of statistical probability in that a writer chooses that level of subject specificity and that combination of words which he feels will convey the most meaning.

Sum up all the digits in the credit card number.If the number is greater than 9 after doubling, subtract 9 from its value.

As you iterate to the left, every other digit is doubled (the check digit is not doubled).Starting from the farthest digit to the right, AKA the check digit, iterate to the left.The calculations in the Luhn algorithm can be broken down as the following steps:

Generally speaking, an algorithm is a series of steps that solve a problem - the Luhn algorithm is a series of mathematical calculations used to validate certain identification numbers, e.g. To find out if a credit card number is valid or not, use the Luhn algorithm. This function should NOT mutate the values of the original array. The purpose of validateCred() is to return true when an array contains digits of a valid credit card number and false when it is invalid. Thanks in advance.Ĭreate a function, validateCred() that has a parameter of an array. Whenever i check valid credit cards it is logging false to the console, but it should be true. I am stuck on the credit card checker project please help.
