A math question that evaluates to 100. Designed to test operator precedence.

An operator precedence parser variation that adds a disambiguation step in order to support overloaded fixities, juxtaposition and other features.

Stack implementation with conversion of Infix expression to Postfix.

Parsers are used to verify the syntax of code or expressions. In this project we used the operator precedence parser algorithm to parse and check the validity of expressions. The backend of the application was built using Flask. The front uses Jinja templates to take the user input and render the parse table along with the steps.
