C language can increase the length of the linear table (example implementation of intersection and complement)
As we all know, the length of C language array can not be increased, which leads to the fact that random storage structure array can not be adopted many times. At this time, many people think of the linked list. We can apply for space to store data and then insert it into the table. It is indeUTF-8...

Algorithm analysis: the longest common subsequence of dynamic programming in C language
Longest common subsequence problem: The following simple question illustrates the basic principle of dynamic programming. On the alphabet Σ, two strings a and B with lengths of N and m are given respectively to determine the length of the longest common subsequence in a and B. Here, A = a ₁ a νUTF-8...
