The number theory problem that God rihkddd explained to me just now. To prevent future forgetting, write it down. The question is to increase the sum of gcd (n, I) from 1 to n. We assume that gcd (n, I) = K, then gcd (N/K, i/K) = 1. Assume that gcd (N/K, x) is 1, then gcd (

Use homogeneous coordinates to transform the Matrix /* Input a character matrix of N * n, rotate it counter-clockwise for 90 degrees, and then output:After calculation, the transformation matrix of the N * n square matrix Rotating 90 degrees is:0, 1, 0, 0,-1, 0-1, 0, 0, the inverse matrix is, 1, 0, 0N-1, 0, 1 0,

There are multiple solutions to this question:First: Mathematical SolutionExample1 2 3 4 = 101 2 3 3 = 9Then we can calculate 4-(10-9) = 3, and 3 is repeated.So we only need to get 1 ~ The sum of N-1 can be calculated using the Gaussian formula, but the premise is to know the sum, then the time complexity of traversing the array is O (n ).If this sequence is not ordered, this method is still common. Second:

1. f (x) Native function existence 2. f (x) level N can be divided into two different interpretations based on the question: 1. The question is about the n-order testability at a certain point, that is, at x = x0. It refers to the existence of F (N) (x0. 2. The question directly says that there are n-order functi

Topic: N team competitions, numbered for 0,1,2 .... N-1, known for their strength-contrast relationships, stored in a two-dimensional array w[n][n], W[i][j] 's value represents a stronger branch of the team numbered i,j. So W[i][j]=i or J, now given their order of appearances and stored in the array order[

Problem description:The so-called subsequence is the sequence that is left after several elements are deleted in the original sequence column. Taking the string "abcdefg" as an example, remove bde to obtain the subsequence "acfg"Now the problem is, to give you a numerical sequence, you need to produce its longest monotonic incrementing subsequence. Input:Multiple groups of test data. The first row of each group of test data is n (1 Output:For each gr

Lazy to translate, to the effect: Top N and SET rowcount n are as fast when there is an appropriate index. But for a unordered heap, top n is faster. Principle to see English. Q. are using the top N clause faster than using SET rowcount N to return a specific number of rows
