Evaluating postfix expression in c
WebQuestion: Mod 9 - Solving 24 with Binary Expression Trees Use Binary Expression Trees (BETs) to solve the game 24. Background BETs We will use BETs, a kind of binary tree used to represent expressions, to solve this problem. In a BET, each internal node corresponds to an operator (e.g. 1+′ or −1 ) and each leaf node corresponds to an operand. WebMar 27, 2024 · Previous; Next ; The postfix expression is a notation for expression used in computers where operator comes after the operands in the expression.
