CodePudding user response:

A. ength> 0 return a value?

CodePudding user response:

This and return a directly; What's the difference?

CodePudding user response:

//can be translated into the following code
If (a. ength & gt; 0)//if the length of a greater than 0
{
Return a.S ubstring (0, a. ength);//return (starting from the index 0, intercept a total length of the substring, isn't that a itself! Redundant)
}
The else
{
return a;//returns a
}

//this is a junk code no matter what the results returned are a, can be directly replaced by return a;
