Here is my tool script code (a C # source that compresses a level two directory):Full of joy, but the result of a shameful failureThe main reason is that I used another C # class file in the MyScript script related functions, that is, the red box in the code, in fact, this is a context is missing (or host problem), the so

ObjectiveThe first feeling is that the difference between the AVL tree is not particularly large, not very intuitive to feel the huge increase in efficiency, as a small obsessive-compulsive patients, or AVL tree more beautiful.But the truth is, the balance is destroyed in the same situation, the red and black trees are really less some of the rotation ...Because the balance is broken when the node is inserted, the red and black tree will choose to rotate or discolor.The AVL tree is rotated only.

can't have a space (when a variable is assigned a value). Sometimes the single quotation marks are sometimes inverted. Ah to pay attention to these small details, experience.Small code is also not easy.If the vast number of readers, you can also look at my brain map, step by step to write a script, will also have some gains.Let's get a beginning. On and off, as the study progresses, the examples will be deepened. Hope your shell level, can have a breakthrough.This article is from a "simple" blo
