The output for converting from infix to postfix expression for some cases is producing a wrong output. Like in this case But the expected output for this is supposed to be

The flaw in your algorithm is that

Over here in your code, we can see that it is pushing the + operator into the stack eventhough there is a (-) operator in there, it is supposed to pop out the( - )operator first and then push in the + operator into the stack.

Wrong output for A ( B + C ) D. The Correct answer is ABC+D. Not ABC+D**.

We would love to contribute bruh.

But could you please remove the GitHub pages since it appears as an infix to prefix converter website on google when someone searches for it. I lost marks in my paper (virtual exams RIP) since I copied from here that's why remove the pages hosting thing please!

Thanks in advance
