EvaluateReversePolishNotation
Evaluate the value of an arithmetic expression in Reverse Polish Notation.
Valid operators are +, -, *, /. Each operand may be an integer or another expression.
Some examples:
[ 2 , 1 , + , 3 , * ] -> ((2 + 1) * 3) -> 9
[ 4 , 13 , 5 , / , + ] -> (4 + (13 / 5)) -> 6
分析：这一题就是写程序计算逆波兰式的结果，遍历表达式，碰到操作数入栈，碰到操作符就从栈顶取出两个操作数，再将计算后的结果入栈，最后栈中剩余的唯一操作数就是计算结果。(.
