modulus 1

Many mathematical formulae can be used in the design, for example, the common golden ratio is one of them. In the design layout of Web pages, we can also get the ideal composition ratio by precise calculation, this article will introduce the use of

1. Defects of large number modulus exponentiation: the introduction of fast power modulus algorithm is proposed from the limitation of the naïve algorithm of large number of decimal modulus, in the naïve method we calculate a number such as 5^1003%31

D. the Child and SequenceAt the children's, the child came to picks's house, and messed he house up. Picks was angry at him. A lot of important things were lost, in particular the favorite sequence of picks.Fortunately, picks remembers how to repair

Convert it to c * x = B-a mod (2 ^ k), and solve the minimum positive integer of the modulus linear equation. Sample Input3 3 2 163 7 2 167 3 2 163 4 2 160 0 0 0 Sample Output0232766FOREVER Equation solving: ax = B (mod n); [ax % n = B % n]Set one

A very interesting phenomenon has been found today.As a division, Python2 and C + + have different divisible results in the case of negative numbers:When I was 5/3,Results for C + +: 1Results for Python2:2(Note that 5/-3 is still available in C + +-1

Vjudge on the topic Link: Huge ModsAttached:Test instructions is not difficult to understand, because the index range is too large, so I think it is necessary to use power Dafa: ab% C = ab% phi (c) + phi (c)% c (B > Phi (c)) ? Later found that

The encryption method of RSA public key is a^b%c; when a/b value is large, it is difficult to evaluate directly, so there are the following algorithms:1: Use the formula (A*B)%c= ((a%c) *b)%c to process each step, as the formula shows ... This
