-Evaluation: Start from the rightmost operator and move left, applying each operator to the appropriate operands. 2.Postfix Notation: -Syntax: Operands precede their operator. Example: 3 5 + (equivalent to 3 + 5
One of the applications of postfix notation is to build a calculator or evaluate expressions in a programming language. In addition, we can evaluate postfix expressions efficiently using a stack data structure. Therefore, postfix notation is effective for implementing algorithms such as postfix notation...
分析: Traverse the infix expression and check if given character is an operator or an operand. If it is an operand, then push it into operand stack. If it is an operator, then check if priority of current operator is greater than or less than or equal to the operator at top of the ...
I need to write a program that reads a file as input and converts prefix to postfix and infix.. I wanted to know if I should do this using trees or think of an algorithm to convert it .. Sep 21, 2008 at 12:15am helios (17607) You mean these three? http://en.wikipedia.org/...
