Convert Infix to Postfix notation

Convert Infix to Postfix notation is a DSA topic. In plain words you use it for a short Convert Infix to Postfix notation example in a short dry-run on paper. Don’t start with a slogan — start with that picture.

Smallest example: the smallest Convert Infix to Postfix notation example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Convert Infix to Postfix notation.

From the example next to this theory: Convert Infix to Postfix notation — big-O describes how work grows with input size — ignore constants.

Trap — only saying “Convert Infix to Postfix notation” with no example. Fix that before you talk about advanced DSA.

Viva: what is Convert Infix to Postfix notation? Then show the smallest Convert Infix to Postfix notation example you can type. Then name the trap.
