If these operations are performed on a one-dimensional sequence, then the line segment tree can be used. But now the question expands these operations to two-dimensional, recalling that the essence of the Line Segment tree is a binary line segment, then for a two-dimensional matrix, expansion should be a quartile matrix.

Iii. Xiaomi mobile phone hardware analysis
Xiaomi's mobile phone has become a star in the recent smart machine product, and its ultra-high hardware configuration is involved.
The body size is 125x63x11. 9mm, and the weight of the whole machine is 149 grams. The camera uses the 4 inch touch screen launched by sharp, with a resolution of 8 54x480 pixels. It is equipped with a GHz Qualcomm snapdrogan System 3 Series msm8260 dual-core processor, with 1 gb ram memory and 4 GB Rom capacity, equipp

NVIDIA launched a tegra product this month that is comparable to that of desktop computers, focusing on mobile devices and other devices. Tegra uses the arm 11 architecture for the smartphone, mid, and netbook markets. NVIDIA said that the tegra processor would have 1
chips has crushed the industry's vision-dominated Nvdia products, such as the current mobile GPU Overlord Tegra K1 compared to the previous test data show that, at 300MHz, Tegra K1 and GX6650 (iPad AIR2) can achieve 115.2GFLOPS FP32 floating-point computing power, and GT7600 can basically be the same as GX6650, so the overall performance is very strong, staggering. After all,

Mathematical Proof]
If R is the circle radius, A, B, and C are the angles of triangles, A/Sina = B/sinb = C/sinc = 2R is obtained from the sine theorem.Therefore, A + B + C = 2R (SINA + sinb + sinc). When r determines that the circumference A + B + C is the largest, the sum is the maximum of SINA + sinb + sinc.Set y = SINA + sinb + sinc, first fixed angle,Y = SINA + sinb + sinc = SINA + 2sin (B + C)/2) Cos (B-C)/2)= SINA + 2cos (A/2) Cos (B-C)/2)Because a is a fixed value, onl
In the previous section, we talked about how to find the path. During discussions with friends, we were not very right. We went a long way. In fact, the code is mainly about determining the direction, for example, the target is on the top right, it should be right first or first, but it will not be processed. If this is done, the effect will be better, but it will inevitably lead to detours. Greedy is like this, not optimal, close to optimal. I also hope that other students will have some commen
The study of iterative methodIterative method is a common algorithm design method for solving the approximate root of equations or equations. Set the equation to f (x) = 0, use a mathematical method to derive the equivalent form x=g (x), and then follow these steps:(1) Select an approximate root of the equation and assign it to the variable x0;(2) The value of x0 is stored in the variable x1, then g (x1) is
Nested calls to C + + functionsC + + does not allow nested definitions of functions, that is, you cannot fully include another function in one function. The definition of each function in a program is parallel and independent.
Although C + + cannot nest definition functions, you can nest call functions, that is, when you call a function, another function is called.
When implementing a function nesting call in a program, it should be noted that before calling a function, you need to declare eac
become the initial point of the second time slice, then on the second time slice on the C point and the new target point to construct a triangle to calculate the new VT, and then into the third time slice, so repeated.Assuming the coordinates of the initial state of the missile and the target are (x1,y1), (x, y), constructs the right triangle Abe, which is used to seek the sine and cosine of the ∠a, because the VT is set by itself, we need to calcula
Note: This tutorial is I try to use scikit-learn some experience, Scikit-learn really super easy to get started, simple and practical. 30 minutes learning to call the basic regression method and the integration method should be enough.This article mainly refers to the official website of Scikit-learn.Preface: This tutorial mainly uses the most basic function of numpy, used to generate data, matplotlib used for drawing, Scikit-learn is used to call machine learning method.
