How to solve infix to postfix expression
WebSep 13, 2024 · The algorithm for evaluation of postfix expression is as follows -. Create a stack that holds integer type data to store the operands of the given postfix expression. Let it be st. Iterate over the string from left to right and do the following -. If the current element is an operand, push it into the stack. WebTransform Infix to Postfix • Algorithm: maintain a stack and scan the postfix expression from left to right – When we get a number, output it – When we get an operator O, pop the top element in the stack until there is no operator having higher priority then O and then push(O) into the stack – When the expression is ended, pop all the
