#227. Basic Calculator II
#Implement a basic calculator to evaluate a simple expression string.
#The expression string contains only non-negative integers, +, -, *, / operators and empty spaces . The integer division should truncate toward zero.
#You may assume that the given expression is always valid.
#Some examples:
#"3+2*2" = 7
#" 3/2 " = 1
#" 3+5 / 2 " = 5
#Note: Do not use the eval built-in library function.

## @param {String} s
## @return {Integer}
