The algorithm for evaluating any postfix expression with a stack is fairly straightforward: While there are input tokens left, read … WebOct 18, 2024 · The algorithm to evaluate a postfix expression is pretty simple. The idea is that you push operands onto the stack until you encounter an operator. Then you pop two operands off the stack, apply the operand, and push the result back onto the stack. When you're done, the final result is on the stack.
