As far as Bada shares are concerned, I have always known that the main positions are heavy, but I have not calculated the details. On Friday, I finally reached the pre-high point. I was shocked when I started to calculate it, at present, the main position of Bada shares is more than 65%. In addition, the 20% chips in the general stock are very stable, so th
I. Question
Set X [1 .. n] and y [1 .. n] is two arrays, each containing N sorted numbers. An algorithm is provided to calculate the O (lgn) Time of the median of all 2n elements in array X and array y.
Ii. Ideas
Solve the problem recursively. The solution scale is halved. When there are four elements left, the solution is obtained,
This paper calculates the lower median, which is characterized:
(1) When n is an odd number, so n = 2 * m + 1, the lower
After nested ScrollView in ListView, set the dividerHeight attribute and calculate the height. listviewdivider
When we need to nest ScrollView in the outer part of the listView, the two scroll effects will affect each other. To avoid this, we usually disable listView scrolling,
Calculate the total height of the ListView and display it completely.

Javascript algorithm question: Calculate the sequence number of any 1-9 N-digits that are not repeated in the combination.
The specific question is as follows:
Select N numbers from 1-9 to Form N-digit numbers that are not repeated. Numbers are numbered from small to large. When you enter any number M, you can find the corresponding number.
. For example, N = 3, M = 213. output: [123 (1), 132 (2), 213 (3), 231 (4), 312 (5), 321 (6)] ---> X = 2
First,

empty and continues into the stack. Note that as long as the sequence is continuously increasing, we need to keep pushing until we encounter an element with I = 4, H [I] = 2 less than the top of the stack.
At this time, the area of the rectangle is calculated. First, the top element of the stack is popped up, t = 3. That is, the green part.
Next, we noticed that the (index pointing) element at the top of the stack is greater than the current I pointing element, so we went out of the stack and
I. method and principle of calculating pi values
Baidu, there are quite a few methods to calculate pi. However, in the hadoop examples code, note that the quasi-Monte Carlo algorithm is used to estimate the PI value.Quasi-Monte Carlo's descriptive Comparison Theory in Wikipedia is difficult to understand.Fortunately, Google found an article on the Stanford University website: Can PI be obtained by throwing a dart? The article is very short, illustrate

Everyone knows that π = 3.1415926 ...... There are infinite digits. In history, many people have been calculating this number, which has always been regarded as a very complicated problem. Now that you have a computer, the problem is simple.The computer can use the series to calculate a lot of high-precision values. For details about the series, see advanced mathematics. The following are famous π series:
Some of them are complicated to
