http://www.51nod.com/onlineJudge/questionCode.html#!problemId=1393The method is fascinating. Also looked at other people's thinking to come out.First consider turning 0 all into-1. Then a prefix is counted and expressed in sum[i].Then the substring starting from the starting point is valid as long as the value of Sum[i] equals 0.If the substring starting point is not 0, then as long as two occurrences of sum[i], the two values must be a valid substrin

1~20 Choose 2 numbers and tell b the two numbers and the product of the 2 numbers. Then ask a know how many of these two numbers are. A said do not know, ask B to know the two number is what? B also said not to know. Then a suddenly reasoned out how many of these two numbers were, and told B he knew the answer.B then also know how many of these two numbers are. May I ask how they reasoned, and what are the

Today in Huawei OJ encounter such a topic, very simple, but always get the best record. So the comparison of their own procedures, ideas and similarities and differences between others, found that there is a big difference, so the record is as follows. Topic-- Enter an int integer that asks how many 1 of the integer's binary is in memory. For example, enter 10, because the binary representation is 1010, there are two

1. Select a serviceSuppose: Our map service has been published with the name Test. As shown in the following:1.1.2-Set the number of processes to publish the cacheRight-click the test service, first stop the service, select Service property, and select the Pooling tab.As shown, we set the maximum number of instances, theoretically the best is the

Problem description There is a robot at the origin of the coordinates. Every second the robot can move to the right to a unit distance, or stay in place. If the robot's current position is on the right side of the origin, it can also move the unit distance to the left. A series of moves (move left, move right, stay stationary) are defined as a path. Ask how many different paths so that nnn seconds after the robot is still at the coordinate origin. The answer may be large, just output the answer

Again to brush face questions, haha.Requirements: Use for loop to print 1-10, each number appears at an interval of about 500ms.Analysis: Research points-closures, block-level scopesMode one, the use of closures + immediately execute the function, his thoughts at that time also think so, but the results do not reflect the interval 500msfor (var i = 1; i After mod
