需求:在一个字符串中, 如果遇到连续重复的字符只出现一个,(不是去重) 例:str1 = 'aabbccddaabbccdd' 输出结果为:‘abcdabcd’ 具体实现代码如下: def func(_str): _list = list(_str) n = len(_list) if n <= 1: print(_str) return list1 = [] for i in range(n-1): if _list[i] != _list[i+1]: list1.append(_list[i…

//通过Map 类实现,通过键值对的方式,可以将输入的字符串的每一个字符,作为键,每个字符出现的次数作为值:如下: public class Find { public static void main(String[] args){ String scan=new Scanner(System.in).nextLine();//获取键盘上输入的字符串: Map<Character,Integer> map = new HashMap<Character,Integer>();//…
