Computers have a variety of traits, including: You can get the digits in reverse order by repeatedly dividing the integer or the quotient from the previous division by the base (2 or 10), and saving the remainders (into an array or push them onto the stack), which will contain the digits (in reverse order). Can you restore data from a deleted file that was previously emptied. Count bits 1 on an integer as fast as GCC __builtin__popcount(int) shows a way where you count iterations of n &= n-1 to clear the lowest set bit, which is faster if there are only a few bits set, even if they're not near the bottom of the register. To do this, 16 digits are needed, and arbitrarily the numbers and letters 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F were chosen as the 16 digits.
