Median is the middle value in an ordered integer list. If the size of the list is even, there is no middle value. The median is the mean of the middle value.Examples:[2,3,4], the median is3[2,3], the median is(2 + 3) / 2 = 2.5Design a data structure that supports the following and the operations: void addnum (int num)-Add A integer number from the data stream to the data structure. Double Findmedian ()-Return The median of all elements so far. For example:Add (1) Add (2) Findme

In multi-threaded programming, we often need to use data sharing. C # in how to implement it? You just need to set the data you want to share to static. The keyword static is as follows: Static queue Q1 = new Queue (); Static int B = 0; Here I define an integer variable B and queue Q1. You can create multi-threaded Code as follows: Mythread ACC; Thread [] MYT; MYT = new thread [10]; Py = new mythread (); Fo

result set Q1. (3) traverse the drive result set Q1 and the driven table T2, and retrieve a record from the drive result set Q1, next, traverse T2 and judge whether there is a matching record in T2 according to the connection condition T2.id = T1.id. If yes, the record is retained. If no matching exists, this row is ignored, then retrieve the next record from

Find the largest common substring in the two strings, for example, "abccade" and "dgcadde". The largest substring is "cad" // Use for to control the loop, which is easier to understand than the following while.

As we all know, it is very efficient to search for ordered sequences using the bipartite method. In addition, the idea of the Bipartite method is applied in many aspects, not only to find a specific data. For example, when we evaluate the zero point of a monotonic function f (x), suppose we know that its zero point is in a range (a, B, then we can use the bipartite method to obtain the root of f (x) = 0. Now, let's look at a practical application. Topcoder SRM338 2nd question, (http://www.topcod
