Each assignement begins with line containing of an integer m (1 Output for each assingnement there are the only one line of output.

Fermat theorem, Euler's function

certificate.Simple and clear. But it's wrong. Because the premise is wrong. Due to n and P reciprocity. Not necessarily n≡1 (mod p)Can only be said that due to N and P reciprocity, exists kn≡1 (mod p) (k|1,2,3..p-1) (according to the above theorem)Example n=2 p=5. There is 3n mod p = 1. and n mod p = 2.Euler functions:function: Enter n, do you want to know how m

Euler's function and Euler's theorem

The following is excerpted from AcdreamerTheorem one: setting m and n is a positive integer of the reciprocity, thentheorem Two: When n is an odd number, there is. Since 2n is an even number, even and even numbers must be non-reciprocal, so only consider the case of 2n and less than its odd-sum, which is exactly equal to the Euler function value of N.Theorem Three: Set P is a prime number, A is a positive integer, thenThe proof of this

That is, if p is a prime number and gcd (a,p) = 1, a(p-1) ≡1 (mod p). then, a power of A and b of the bn power of the product and take the remainder, respectively, the use of two fast power. #include #include#includeusing namespacestd

An accurate statement of the fundamental theorem of calculus _ synthesis

In our country, calculus textbooks often say the basic theorem of calculus is "Newton-" Leibniz formula, and the spirit of the theorem is avoided. In essence, the core idea of this important theorem is that the numerical calculation of definite integral can be replaced by the technique of "symbolic integration", which saves a lot of numerical cost. The first part

Complexity of algorithm and Master theorem _ complexity

, depending on the attributes of the input data itself. Then there is the difference between the worst-case scenario, the best case, and the average algorithm complexity. They reflect the efficiency of the algorithm from different angles, and each has its own usefulness and limitations. Sometimes it is possible to roughly estimate the performance of an algorithm using the worst-case scenario and the optimal algorithm complexity. For example, an algorithm in the worst case time complexity of θ (n

Further, if the graph is a simple graph, it is said that the sequence can be simply graphical. http://It is simpler to determine the graph: d1+d2+...dn=0 (MO

Time complexity of analysis algorithm--The theorem of the item

In the analysis of the time complexity of the algorithm based on the recursive equation, the equation is common to the following forms,T (n) = A * T (n/b) + f (n)A³1,b > 1,f (n) is generally a simple functionThere are 2 ways to calculate the complexity of time. One is to use recursive tree, layer by generation into the original, and eventually form a series,And then use a function to express, get T (n).The second is the Master Method, which applies the item
