Link to the question: Ultraviolet A 11426-GCD-Extreme
Question: Give n, ask Σ I! = Jngcd (I, j)
Solution: f (n) = gcd (1, n) + gcd (2, n) +? + Gcd (n? 1, n)S (n) = f (2) + f (3) +? + F (n)S (n) = S (n? 1) + f (n)The problem is converted to how to calculate f (n). For a n, the enumerated factor can multiply the number of upper.

Qing ------ peak and extreme of China's ink and landscape Animation
Comment by emilmatthew
If I want to describe the subject of the ink animation that was shot in the last month, I think these eight words are the most accurate: the nature of the TAO, the unity of Heaven and Man.For such a great work, any word of praise will be too clumsy, or let us immerse ourselves in the ink landscape, experience that quiet, high-distance, indifferent and smooth .
XP eXtreme Programming has four values, five principles, and 13 Best Practices. One of the best practices is that working 40 hours a week makes developers most happy, A best practice opposed by managers.
Overtime and overtime have long been common for developers and are also the most common strategy for managers. Overtime seems to be a potential rule in the IT industry, even if companies do not explicitly say that, it will also become the default ru

Because I am too fond of food, the K value will only be sorted
So I used sorting to calculate the k-th K
Description
Given the value of N, you will have to find the value of G. The meaning of G is given in the following code
G=0;
for(i=1;i
for(j=i+1;j
G+=gcd(i,j);
/* Here gcd () is a function that finds the greatest common divisor of the two input numbers */
Input
The input file contains at most 20000 lines of inputs. each line contains an integer N (1
Output
For each line of input produce one line of output. This line contains the value of G for the corresponding N. The value o
turtles and rabbits is constant. VT indicates the speed of the rabbit, VW indicates the speed of the tortoise, VT = VW + a (a> 0)
The tortoise runs B before the rabbit. After B, the rabbit starts from the starting point. The rabbit's time TT is the time of the tortoise minus B. Tt + B = TW (B> 0)
Distance S is the product of speed and time. St = Vt * TT
Sw = VW * TW
Time of St = Sw.
Sw-ST = 0 ====> VW * Tw-Vt * TT = 0 ====> in this case, the solution is that the rabbit and the tortoise are at t
same time. What we don't know about is assumption. Submitted to the user for review. Unnecessary features are cut off through negotiation: The time is so short, the architecture and performance requirements are high, how can we make so many demands? Soon the demand was under control, and our functions were very clear.TIPS: There are two reasons for this project to be able to control the demand: (1) Use the requirement prototype development and quickly organize the UI based on your understanding
In the last two weeks, I have read 73 extreme programming papers, 68 of which mainly write Pair programming papers.
Among these papers, I have seen articles from various countries, including European, North America, Australia, and a small number of Asian papers, I have seen about four or five papers from domestic universities that cooperate with foreign universities or research institutions.
The names of Chinese universities are not mentioned.

Acer's 13-inch Swift 7 is the lightest, thinnest and most portable ultra-extreme in the market, coupled with a fan-less design, so it doesn't have much noise to run. At the same time, the Swift 7 design is also very stylish, and keyboard feel is also I experienced in all the superb level of the super, and the large touch pad is also very comfortable to use.
But that does not mean Swift 7 is perfect, and of course there are drawbacks.
First, Swift 7

of this paper for solving a single equation.3. Using Newton method to find the extremum of a functionIf you use ▽f (x) to represent the gradient vectors of the function f (x), you can get an iterative formula for finding the extremum of the function by taking it into the ordinary Newton iterative formula:Consider the following:Iterative formulas can be further simplified in form:whereH(f) represents the Haisen matrix (Hessian matrix) of function f (x1,..., xn).For specific issues, the previous
lot of experience, including a deep impression is "application extreme" and "browsing simplification." Rich and diverse applications, can fully meet the needs of the Ashes-level users, in this era of application of the king, so that the browser has been reborn. In addition, the browser interface is simple and clean, people have the feeling of using "broadband". In the "intelligent" and "security" aspects, Baidu Browser performance is also quite good.
