Expression tree to postfix
WebApplication of these ideas? As we just saw, postfix expressions without brackets are easy to evaluate. A similar algorithm applies for pre-fix expressions. Infix expressions (with or without brackets) are trickier to evaluate, since you need to incorporate precedence ordering rules for the different operands. Details omitted.
