假设一个算术表达式中可以包括三种括号：圆括号“（”和“）”，方括号“[”和“]”和花括号“{”和“}”且这三种括号可以按任意的次序嵌套使用（如：…[…{…}…[…]…]…[…]…(…)…）。编写判别给定表达式中所含括号是否正确配对出现的算法（已知表达式已存入数据元素为字符的顺序表中）-Suppose an arithmetic expression can include three types of brackets: parentheses " ("　and " )" , in square brackets " ["　and " ]"　and braces " {"　and " }"　and this can be any of three brackets order of nested (such as: ... [... {...} ... [...] ...] ... [...] ... (...) ...). The preparation of discrimination contained in the given expression appears in parentheses matching algorithm is correct (known expression for the character data elements have been deposited in the order form)
