The GCC compiler compiler has four stages, preprocessing, compiling, compiling, linking. The preprocessing phase compiles the included header files in the source code, such as Stdio.h, in the compilation phase, when GCC first checks the code for normalization, syntax errors, etc. to determine the actual work to be done by the code, and when the check is correct, GCC translates the code into assembly language, and the assembly phase is generated during the compile phase.

Public classSolution {//This is similar to N-queens, this is more simple, just ask for the number of solutions, so there is no print step//Note: The parameters of the IsValid function, and the range of I in the function//a[] Meaning, can represent the line of a chessboard intRes; inta[]; Public intTotalnqueens (intN) {A=New int[n]; Nqueens (0, N); returnRes; } Pu
because the class object is simple interest, and within the scope of the application, there is only one instance of class. Each class has only one class object, so you can use = =, and each class object has only one meta class associated with it. Try to use the type information query method to determine the object type, rather than directly comparing the object, because some objects may implement the message forwarding function, if the object returned by the method class directly compared with
N-queens IIFollow up for n-queens problem.Now, instead outputting board configurations and return the total number of distinct solutions.Idea: Solve the problem, the problem will be solved, or that the problem is more simple.The specific code is as follows:public class Solution { int count = 0;public int totalnqueens (int n) {int[] x = new Int[n];queens (x, n, 0); return Coun t;} void Queens (int[] x,int n,int row) {for (int i = 0; i Trick: This problem has a very simple solution, do not look

This function is used to find the location where [first2, last2) appears for the first time in [first1, last1.
It is equivalent to the position where a subsequence first appears in a sequence.
If the match succeeds, the first matched element in [first1, last1) is returned.
Otherwise, last1.
The behavior is similar:
