算法题018 -- [Evaluate Reverse Polish Notation] by java

题目在反向波兰表示法中计算算术表达式的值。有效的运算符是+，-，*，/。每个操作数可以是整数或另一个表达式。举例["2","1","+","3","*"]->((2+1)*3)->9["4","13","5","/","+"]->(4+(13/5))->6分析其实就是计算符号前相邻两个数的值，再push进入stack，直到循环结束，stack中只会存在一个最终计算的值。具体思路，以["2","1"

Reverse Polish Notation (后缀表达式)

标准的表达式如"A+B"，在数学上学名叫中缀表达式（InfixNotation），原因是运算符号在两个运算对象的中间。相对应的还有前缀表达式（PrefixNotation）,如："+-A*BCD"，转换成中缀表达式为："A-B*C+D"；后缀表达式（PostfixNotation），比如前所述的中缀表达式转换为后缀表达式为："ABC*-D+"。为了纪念波兰数学家鲁卡谢维奇（JanLukasiewi
