首先是写一个分割字符串的函数,返回table类型 CREATE OR REPLACE FUNCTION fn_split (p_str IN VARCHAR2, p_delimiter IN VARCHAR2)RETURN ty_str_splitIS j INT := 0; i INT := 1; len INT := 0; len1 INT := 0; str VARCHAR2 (4000); str_split ty_str_split := ty_st
boolean matchBracket( String str ) { Stack stack = new Stack(); try { for ( int i = 0; i < str.length(); i++ ) { char curChar = str.charAt( i ); switch ( curChar ) { case '[': case '{': case '(': stack.push( curChar ); break; case ']': if ( !stack.po
