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...
Implement a basic calculator to evaluate a simple expression string. The expression string may contain open(and closing parentheses), the plus+or minus sign-, non-negative integers and empty spaces. You may assume that the given expression is always valid. Some examples: "1 + 1" = 2 " 2-...
(2)乘除需要在后一个数字入栈后处理; (3)最后栈内剩余为加减法,只需要一步步弹出即可,需要记住一次只弹出一个数字和符号,不能两个数字运算,在I中有说明,遗忘的话可以点击->Basic Calculator I (4)需要对最后一个数字进行特殊处理,因为前面的方法只有检测到有符号的时候才会将数字如栈。 代码(后面有优化版):...
