Output each set of test data outputs a positive integer that represents the minimum cost of laying the line that meets the headmaster's requirements.

Topic:Counts the number of occurrences of a number in a sorted array. For example input sort array {1,2,3,3,3,3,4,5} and number 3, because 3 appears in this array 4 times, so output 4.Solution One: O (n)Sequential traversalSolution Two: O (LOGN)Find the first 3, and the last 3, and then calculate the number.#include The point of a sword 38-number of occurrences in a sorted array

logical error in the subordinate business.Synchronous operationConcurrent operation also need to maintain the consistency of data, more or less involves synchronous operation. Proper use of atomic operations and proper use of exclusive and read-write locks is also a big challenge.Coordination and communication between threads, especially state synchronization, are more difficult. We see the implementation of thread pool threadpoolexecutor in order to solve the execution state of various threads

As above, the list structure may store the same elements, but the set class requires that the same elements cannot be stored, so in order for the list structure to serve

Years ago, MIT researchers have confirmed that fonts affect our feelings: bad fonts make people unconscious, and good fonts make us happy. If the font can affect our mood, it will also affect the user experience. A few weeks ago, I decided to explore how much the font would affect the user experience. Through a series of comparative tests, my website traffic increased by 38%, just in case of changing the font. Before I start detailing my tests, let'

created a abovethefold selector to select an element that is not visible: The nbsp; code is as follows: $.extend ($.expr[': '), {nbsp;abovethefold:function (EL) { nbsp; return $ (EL). Offset (). Top ; '). Appendto (' head '); 35. It's a good way to avoid loading extra code in a different file with JavaScript code, just load them when you need them. This way you don't load unnecessary code and selectors. It also makes it easier to manage code. 36, compressed into a main JS file, the number of do
