5 dni temu · Modulus on Negative Numbers. Last Updated : 02 Jul, 2024. The modulus operator, denoted as %, returns the remainder when one number (the dividend) is divided by another number (the divisor).
1 dzień temu · Sum the digits in the even positions (excluding the check digit). \[ 2 + 1 + 8 + 2 + 1 = 14 \] Step 6/9 Add the result from Step 4 to the sum of the even-position digits from Step 5. \[ 33 + 14 = 47 \] Step 7/9 Find the smallest number that, when added to the result from Step 6, makes it a multiple of 10. This number is the check digit. \[ 47 ...

5 dni temu · You are given two integer numbers, the base a (number of digits d, such that 1 <= d <= 1000) and the index b (0 <= b <= 922*10^15). You have to find the last digit of a^b. Examples: Input : 3 10. Output : 9. Input : 6 2. Output : 6.
4 dni temu · The length of the repetend (period of the repeating decimal segment) of 1 / p is equal to the order of 10 modulo p. If 10 is a primitive root modulo p, then the repetend length is equal to p − 1; if not, then the repetend length is a factor of p − 1. This result can be deduced from Fermat's little theorem, which states that 10 p−1 ≡ 1 ...
3 dni temu · Wilson's theorem states that. a positive integer n > 1 n > 1 is a prime if and only if (n-1)! \equiv -1 \pmod {n} (n−1)! ≡ −1 (mod n). In other words, (n-1)! (n−1)! is 1 less than a multiple of n n. This is useful in evaluating computations of (n-1)! (n− 1)!, especially in Olympiad number theory problems.
