is the art of data structure. In the backtracking of large-scale continuous data, we can convert it into a Recursive Generation Method and reverse thinking operation, which is the art of algorithms. 3. the smartest person to use the simplest things is clearer than the person who solves complicated problems with complicated methods. Section 3,ProgramConstruction and interpretationLet me explain the principle of the above program in detail. OK. For example, if we want to calculate the nu

following path object inserts a polygon slice as required, Take a look at the effect of the following illustration to insert a new multilateral slice. 5, Next, we undo just the operation steps, back to the 2nd step of the operation. Then the menu "Modify | Synthetic path | merge" command is executed on the top two objects, followed by the menu "Modify | synthetic path | punch" command for the following two objects, the edit area object is now shown

1. In JavaScript, the arguments object is a more specific object, which is actually a built-in property of the current function. Arguments is very similar to an array, but is not actually an array instance. Can be confirmed by the following code (of course, in the function Funcarg, the call arguments is not necessarily written funcarg.arguments, write arguments directly).1 ARRAY.PROTOTYPE.TESTARG = "Test"; 2 function Funcarg () {3 alert (FUNCARG.ARGUMENTS.TESTARG); 4 alert (Funcarg.argu
