Question: Find a continuous array, maximum continuous sum.
(1) O (N3) algorithm:
Using the method of exhaustion, the efficiency of this method is the worst.
The Code is as follows:
#include
(2) O (n2) algorithm:
Analysis: Suppose Si = A1 + A2 +... + AI, then ai + AI + 1 +... + AJ = Sj-Si-1. This formula indicates that the sum of consecutive subsequences is equal to the difference between two prefixes.
With this idea, we can remove the innermost lo
floyed algorithm O (N3) abbreviation floyed (Freud) algorithm, is the simplest shortest path algorithm, can calculate the shortest path between any two points in the graph. The time complexity of the floyed is O (N3), which is suitable for cases where negative edge rights are present. Algorithm analysis Ideas explained: Three-layer cycle, the first cycle of the middle point K, the second third layer of the

that as long as the r+w>n, can guarantee the availability of the cluster. The values of N, W, R can be set. If you pay attention to the efficiency of reading, you can set the value of r smaller; If you pay attention to the efficiency of writing, you can set the value of W smaller. NWR does not guarantee consistent data. If R=n and w=n, then consistency can be guaranteed.Vector clockFor small or low-demand distributed systems, the time stamp can be used to ensure consistency of data between repl
transformer is that the first and second winding of the switch power transformer will generate a high back potential when the switch K is switched off, this back-force is produced by the magnetic energy stored by the excitation current flowing through the first coil winding of the transformer. Therefore, in Figure 1-17, in order to prevent the generation of the Back-voltage force breakdown switch device when the control switch K is turned off, add a back-voltage energy absorption feedback coil
, emotional, and intellectual peaks occur. Then a start date is given,
It is required to calculate the minimum number of days after which the three peaks will appear at the same time from this day.
Problem Analysis
First, we need to know that the period between any two peaks must be an integer multiple. Assume that the nth day of the year reaches the peak value, and the next time the peak value is reached
Between them is n + tk (T is the cycle, K is any positive integer ). Therefore, the day (s)

result divided by 3), then the three products are added (15*2+21*3+70*2) and 233.3. Divide 233 by 3,5,7 Three least common multiple 105 to get the remainder 23, i.e. 233%105=23. The remainder of 23 is the decimal number that meets the criteria.We split the "grandson problem" into a few simple little questions, starting from scratch and trying to speculate on how the ancients deduced the solution.First, we assume that N1 is a number that satisfies the divide by more than 3 2, such as 2,5,8 and s
and 233.
Divide 233 by 3, 5, and 7 by the minimum public multiple of 105, and obtain the remainder 23, that is, 233% 105 = 23. The remainder 23 is the minimum number that meets the condition.
Analysis:
We split the "Sun Tzu's question" into several simple small problems, starting from scratch, trying to speculate on how the ancients pushed this solution.
First, let us assume that N1 is a number that satisfies dividing by 3 more than 2, such as 2, 5, 8, and so on, that is, an arbitrary numbe
that satisfies division by 3 and more than 2, such as 2, 5, 8, and so on. Similarly, we assume that N2 is a number that satisfies the division by more than 5 3, and N3 is a number that satisfies the division by more than 7 2.
With these assumptions, we first analyze from the perspective of N1. If we know that N1 is satisfied by dividing by more than 3 2, can we make the sum of N1 + N2 still meet the condition of dividing by 3 + 2? So that the sum of

In a namespace, we can also use an alias to refer to an existing namespace or some other type of data.
The use format for aliases is as follows:
The Using alias = an already existing type;
For example: using Soholife = System;
Here are a few examples to deepen our understanding:
Namespace N1. N2
{
Class A {}
}
Namespace N3
{
Using A = N1. N2. A
Class B:a {}
}
Here, in N3, A is the alias of N1
