I was a senior student's previous project and I'm redoing it again. The result suddenly showed an exception, which I was puzzled. Why did it happen unexpectedly? I used it well yesterday and didn't even touch the source code. So I started a query

Given preorder and inorder traversal of a tree, construct the binary tree. Note:You may assume that duplicates do not exist in the tree. There are two solutions to this question: 1) recursive solution (relatively good) follow the manual simulation

Static is a function that is added to a non-class member function. Because the static version of the class member function has other purposes), it is equivalent to the role of anonymous space-Information Hiding. Translation into the vernacular
