Jiang Yongjiang Altera Cup National Graduate Electronic Design Competition has a simple question of "representing-37 as a three-digit complement code. The instructor with a score raised an objection to the answer as soon as he came up, believing that 1122 (3) The result is incorrect, because "except the highest sign bit", 122(3) = 1 × 32 + 2 × 31 + 2 × 30 = 17. This shows that there are problems in our long-term theoretical teaching of digital circuit

Topic links Topic: Of the 9 numbers obtained by the first digit of the permutation, six are prime numbers: 13,23,43,53,73 and 83. By replacing the third and fourth digits of the 56**3 with the same number, this five-digit number is the first number that can get seven prime numbers, the prime numbers are: 56003, 56113, 56333, 56443, 56663, 56773, and 56993. So the smallest of the 56003 is the smallest prime

Given an integer n, count the total number of digit 1 appearing in all non-negative integers less than or equal to N.For example:Given n = 13,Return 6, because digit 1 occurred in the following numbers:1, 10, 11, 12, 13.Hint:1. Beware of overflow. Problem Solving Ideas:To see the answer. Very burning brain, did not see very clearly.This problem is actually equivalent to a law-finding problem. So to fi

Maybe all of us who care about rice know a corn auction, in an auction, five digital domain names have been raised to a day, but how many people know what the inside story is? Some insiders say that this is a play played by XXX's own company or some of the rice farmers who are eager to inject five meters. What really plays is not them but the viewers next to them.1. Currently, there are several websites u

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 multiplied by 1, then respectively, 1,2,1,2,1,2;2, if each digit multiplied by the weight a

(1*3*9*11*13*...) Mod 10 = (1*3*7*9*1*3 *...) mod 10. We list the remainder table,1 3 1 9 9 7 9 1 1 3 1 9 9 7 9 ....... We found that every eight mod 10 results in a loop.After calculating the odd number of results, let's look back at the number of 2 and 5 to be multiplied. Pairing 2 and 5 is all N.! The value 0 is followed by the number 2. If the remaining two exist, consider that the single digit of 2 ^ N is 2 4 8 6 2 48 6 ...... Every four items h
