Output − Convert infix expression to postfix form. Begin initially push some special character say # into the stack for each character ch from infix expression, do if ch is alphanumeric character, then add ch to postfix expression else if ch = opening parenthesis (, then push ( into stack...

The idea is to use thestack data structureto convert an infix expression to a postfix expression. The stack is used to reverse the order of operators in postfix expression. The stack is also used to hold operators since an operator can’t be added to a postfix expression until both of its...
Infix to Postfix Converter This JavaScript program converts infix expressions to postfix notation. It utilizes a stack-based approach to handle operators and parentheses. Approach Input: The user provides an infix expression (e.g., 3 + 4 * (2 - 1)). Tokenization: The input expression is spl...
