Instead, I scan the board from lefttoright and top to bottom (twice, to get both horizontal and vertical words).
我的方法是,从左到右,从上到下对谜板进行扫描(两遍,这是为了得到垂直方向和水平方向的词)。

Lexical analysis of the main tasks are: toscan source code character by character from lefttoright, resulting in one word (Token), also check the source of lexical errors.
Scan the page diagonally from top leftto bottom right - This is the direction the eye is automatically trained to read (of course, it's the opposite in some cultures).
