How to evaluate postfix expressions java
Web7.2. Postfix Expressions¶. When we write arithmetic expressions, such as 5 + 2, we write them in what is known as infix form: the operator + goes in between the operands 5 and 2. But there are other ways to write expressions, and here we will look in detail at a form known as postfix.In a postfix expression, operators come after the operands, e.g. 5 2 … WebEvaluate a postfix expression. Write code to evaluate a given postfix expression efficiently. For example, 82/ will evaluate to 4 (8/2) 138*+ will evaluate to 25 (1+8*3) 545*+5/ will evaluate to 5 ( (5+4*5)/5) Assume that the postfix expression contains only single-digit numeric operands, without any whitespace.
