Run it through valgrind and you'll see a bunch of invalid read errors. You need to advance the iterator before you erase the element from the set. You can use the return value from set.erase() like this.

First of all , Thanks for helping .. Secondly, Above is the link of my recent submission as per your advice . I have corrected this as you said yuizy but i am not getting anything apart from runtime error.. And added to this IS , that my code is perfectly running on my PC..
You still have the same issue — you're advancing the iterator after erasing the corresponding element from the set. The reason it works on your PC is that it's undefined behavior, and would most likely cause a runtime error on your PC as well with bigger inputs. It seems you didn't perhaps understand my code, so here's a link with a few alternative solutions to the issue as one of them might be easier to understand: http://stackoverflow.com/questions/2874441/deleting-elements-from-stl-set-while-iterating.
Thanks yuizy ..and sorry for late reply..
