how to find modulus of number

Original Address http://www.cnblogs.com/flytrace/p/3387748.html I'm a stupid man. It is often more effective to speak to a dumb person after they have understood something. Before you see it, you have the basics of lighting.>> world/object space

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

BackgroundRecently, in a Java exercise, you see such a problem: What's the output when this statement executed:System.out.printf (-7% 3); We are all familiar with the calculation of positive integers, but for the calculation of

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

Knowledge overviewWell, I admit that this is my third day winter vacation on the knowledge, but I am now a tall (winter vacation, but I have been selected in the province ...) ）Well, this is an algorithm for finding discrete-mode logarithmThe
