brackets matching in a string

Brackets matching in a string refers to the process of ensuring that all opening brackets have a corresponding closing bracket in the correct order. For example, the string "([]){}" is properly bracketed, while "([)]" is not, because the closing ")" does not match the opening "(".

There are several algorithms for checking whether a string has properly matched brackets. One common approach is to use a stack data structure, which allows you to keep track of the opening brackets as you encounter them and then check whether each closing bracket matches the most recent opening bracket. If all brackets match properly, then the stack will be empty at the end of the string.

Macro parameter not in brackets

回答: 定义宏时，参数名应该放在括号内。如果参数名不在括号内，宏将无法正常工作。 一个宏的定义应该以宏名开头，如果宏定义需要参数，可以在宏名后面指定参数的名称，用逗号或空格分隔。可以通过在参数名后面加上`=deflt`来为宏参数提供默认值。不能定义两个同样的宏名，除非在两个定义之间使用`.purgem`指令进行清除。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

if e not in ops and e not in brackets:

This is a conditional statement that checks if the variable "e" is not present in the list "ops" and is also not present in the list "brackets". If both conditions are true, the code block associated with this statement will be executed.
