假设我们现在有两个文件 a.txt .b.txt a.txt 中的内容如下: a c 1 3 d 4 b.txt 中的内容如下: a b e 2 1 5 # Example 01 计算并集: [root@VM_81_181_centos ~]# sort -u a.txt b.txt 1 2 3 4 5 a b c d e [root@VM_81_181_centos ~]# # Exmaple 02 计算交集: [root@VM_81_181_centos ~]# grep -F -f a.t
You are given an integer array sorted in ascending order (may contain duplicates), you need to split them into several subsequences, where each subsequences consist of at least 3 consecutive integers. Return whether you can make such a split. Example
