Get the corresponding program statement from line number of a source file

Hi,

I've the line number of a source file and I want to get the corresponding "Stmt" object. There may be more than one program statement in a source line, but in my use case, it's guaranteed to be one program statement in the given source line from the user.

A brute force way can be iterating over all the statements and trying to match the source line number. But I'm just wondering is there a nicer and more efficient way to do this.

Thanks
Riyad
