把一个长字符串分解成若干个固定长度的短字符串,由于事先不知道长字符串的长度,以及短字符串的数量,只能使用List. public static void get_list_sbody(String s){ // 计数变量 int num = 0; // 每行的字符数 int r_num = 27; // 字符串 String sx = new String(""); lst_sbody = new ArrayList(); char[] cr =s.toCharArray(); for
题目: 求一个数组的最长递减子序列比 , 如随机生成一组序列 {8,9,6,3,6,2,3,4} 求得最长递减序列 {9,8,6,4,3,2} list=[3,3,3,3,6,2,3,4] //冒泡排序 n=len(list) for i in range(0,n-2): for k in range(0,n-1): if list[k+1]>list[k]: list[k+1],list[k]=list[k],list[k+1] print(list) result=[] for i in
