The following:Regardless of the large data range, first we can think of its DP solution, Dp[i][k] indicates that the first I number is divided into the maximum score of the K segment, then the transfer equation is:Dp[i][k]=max (dp[j][k-1]+sum[j]* (sum[i]-sum[j));However, this is obviously the kxn^2 algorithm, for 100000 of the data even if K only 200 will be timed out, so we have to reduce the one-dimensional complexity to make the algorithm into NXK complexity, The complexity of reducing the dy

between the inserted node and the root node may be changed. We need to find the first node that breaks the balance condition, which is called K. The height difference between the two Subtrees of K is 2. There are four situations of imbalance: 1. Insert the left subtree of K's left son once. 2. Insert the right subtree of the Left son of K 3. Insert the left subtree of the right son of K once. 4. Insert the right subtree of K's right son once. Case 1 and case 4 are symmetric and require a single

Write in front A certain object is uniquely determined by two IDs, how do you handle this data structure to quickly find and conserve memory? Let's start with a stupid method--a string to deal with. It's easier to think about (I think the simplest and most simple and rough way to do this is to use string to engage in it). fmt.Sprintf("%d_%d", id1, id2) That's it. stored in a string to save, when the query compariso

perform well in other regions. A common method of compensation is to design multiple controllers, each oriented to a specific combination of operating conditions. They switch between real-time as the situation changes. Access to this technology is a traditional example of scheduling. The following example shows how to coordinate multiple model predictive controllersThe system is composed of two objects M1 and M2 respectively connected to two separate springs

If you do not draw the sine/cosine curve in this article, you can look at this first: the console draws the sine/cosine curveSo, if you want to display it at the same time, we may need to draw 3 or 4 points in the same line. My thinking is relatively simple, but the algorithm looks very very untidy, but also hope to get everyone's help ...I divide the entire graph into 4 layers, drawn from top to bottom, by the square root two and negative two of the square root of the y equals two points and th

. Evaluate f (x) First, f' (x) = 1-100/X2, and then f' (X) = 0 find the field x = 10 (x =-10 ). Because f (x) has a minimum value and only one resident point, when x = 10, f (x) gets the minimum value, and the minimum value is 18. This answers this question. In fact, the result of 10 is easy to see directly. When there is only one piece, we divide the entire building into a section with 100 floors. When there are two pawns, we have a lot of division, but no matter how we divide them into

, we can continueB and R perform the remainder operation. After a finite number of duplicates in this process, we can finally get the result of r = 0, and we will get the maximum public approx. of A and B.

Then a = K1 * GCD, B = k2 * GCD LCM = A * T1 =
