python之string模块的find 函数原型:find(str,pos_start,pos_end) 解释:str:被查找“字串”(气味字符串的函数);pos_start:查找的首字母位置(从0开始计数。默认:0);pos_end:查找的末 尾位置(不包括末尾位置。默认-1) 返回值:如果查到:返回查找的第一个出现的额位置,否则,返回-1。
(4)asciiChars用到哈希表思想,用来记录p中每一种字符分别有多少个。详见《如何判断两个String是否是Anagrams》一文。 代码: publicstaticList<Integer>findAnagrams(String s, String p) { List<Integer> result =newArrayList<Integer>();intNumberOfDeference = p.length();//差异度指数intleft=0,right=0;//...
