The following describes two different greedy strategies for solving the minimum spanning tree. The concept of the Minimum Spanning Tree is not described. The following describes the two algorithms. In programming, the flag of a node is used to

Class About the system path delimiter. , Use the Backslash "" as the path separator, such as "", but the backslash in it indicates the escape, so you need to use ":" To represent the path in the program. You can also use ":" To represent the path.

Preface a few days ago, the blogger saw Uncle mouse examine the compilation of atoi on Sina's meager page. Zhou sibo also had to interview Alibaba (ps: although the blogger is in the LNMP direction, but I am still confident that I can work together).

(A + B) % n = (a % n) + (B % n) % n (a-B) % n = (a % n) -(B % n) + n) % nab % n = (long) (a % n) * (B % n) in % n, note that the value of a % n * B % n may exceed the modulo input positive integers n and m, and output the value of n mod m. N #

1. The reference itself is implemented by a pointer: The reference is a read-only pointer. Example: Int d = 123; Int & e = d; // reference Int * const e = d; // read-only pointer. e points to d. You cannot change e to another variable.   2. const

The mechanism can also be explained: Because it executes the fillStackTrace method, it needs to record the snapshot of the current stack, while the String class directly applies to create a memory creation object, and the exception class is slow.
