  #150. Evaluate Reverse Polish Notation
  #Evaluate the value of an arithmetic expression in Reverse Polish Notation.
  #Valid operators are +, -, *, /. Each operand may be an integer or another expression.
  #Note:
  #Division between two integers should truncate toward zero.
  #The given RPN expression is always valid. That means the expression would always evaluate to a result and there won't be any divide by zero operation.
  #Example 1:
  #Input: ["2", "1", "+", "3", "*"]
  #Output: 9
  #Explanation: ((2 + 1) * 3) = 9
  #Example 2:
  #Input: ["4", "13", "5", "/", "+"]
  #Output: 6
  #Explanation: (4 + (13 / 5)) = 6
  #Example 3:
  #Input: ["10", "6", "9", "3", "+", "-11", "*", "/", "*", "17", "+", "5", "+"]
  #Output: 22
  #Explanation: 
  #  ((10 * (6 / ((9 + 3) * -11))) + 17) + 5
  #= ((10 * (6 / (12 * -11))) + 17) + 5
  #= ((10 * (6 / -132)) + 17) + 5
  #= ((10 * 0) + 17) + 5
  #= (0 + 17) + 5
  #= 17 + 5
  #= 22
