消除左递归得到后缀式
- 解法:对原文法消除左递归,根据消除左递归后的等价文法建立语法树,而后对此语法树 进行后根遍历,即可得到后缀式.- Solution: Eliminates the left recursion to the original grammar, after equal in value grammar establishment grammar tree which eliminates the left recursion, aft

逆波兰表达式
- 计算用运算符后缀法表示的表达式的值。后缀表达式也称逆波兰表达式,比中缀表达式计算起来更方便简单些,中缀表达式要计算就存在着括号的匹配问题,所以在计算表达式值时一般都是先转换成后缀表达式,再用后缀法计算表达式的值。如:表达式(a+b*c)/d-e用后缀法表示应为abc*+d/e-。只考虑四则算术运算,且假设输入的操作数均为1位十进制数(0—9),并且输入的后缀形式表达式不含语法错误-calculated Operators suffix
