 Strings made from three characters 2019-12-10 Kelley pose la question :Hi, I vaguely remember some formula for determining all the possible combinations of a set of numbers (or whatever). If I have 3 numbers (0 - 2), then I have 0, 1, 2, 00, 01, 02, 10, 11, 12, 20, 21, 22, 000, 001, 002, 010, 011, 012, 020, 021, 022, 100, 101, 102 and so on. What is the formula for determining all potential results? Thank you!! KelleyPenny Nom lui répond. Strings of characters 2015-12-28 Ali pose la question :If I have an app and offer a two, three and four digits name and it can be only number, letters or both? I want to know how many options will I have for each? For example the two digits: aa, 11, a1 or 1a the three digits: 111, a2a, 222 the four digits: 1111, 2ge3 or 1234 So if I used all the letters and all the numbers but nothing starts with a zero How can I calculate them separately? Or what's the result for each? Thank you AliPenny Nom lui répond.
