} 解法:FindSubString() 函数就是要找到一个先递增再递减且递增和递减的数量相等的回文序列,例如: ABCDCBA ,先是 后一项 = 前一项 ASCII 码 +1 , 后是 后一项 = 前一项 ASCII 码 -1 ,才能返回回文子串的长度,否则返回 0 。 ModifyString() 函数不断寻找上述类型的子串,如果不满足条件,就 *p2++ = *p...
11. substring(int beginIndex) 和 substring(int beginIndex, int endIndex) 返回此字符串的一个子字符串。 substring(int beginIndex) 截取的是从binginIndex索引开始到结尾的字符串; substring(int beginIndex, int endIndex) 截取的是从beginIndex索引开始到endIndex索引的字符串。 System.out.println(str.substrin...
SELECT*from test whereFIND_IN_SET('20',btype) 当然它的返回值为null,因为字段中没有这个值 FIND_IN_SET和like的区别 like是广泛的模糊匹配,字符串中没有分隔符,Find_IN_SET 是精确匹配,字段值以英文”,”分隔,Find_IN_SET查询的结果要小于like查询的结果。
System.out.println("m.child->>"+str.substring(m.start(),m.end())); }else{ System.out.println("m.find->>false"); }//str.matches()底层还是:Pattern p = Pattern.compile("[0-9]+"); Matcher m = p.matcher(str);System.out.println(str.matches("[0-9]+")); ...
