假设正读和反读都相同的字符序列为“回文”，例如，‘abba’和‘abcba’是回文，‘abcde’ 和‘ababab’则不是回文。假设一字符序列已存入计算机，请分析用线性表、堆栈和队列等方式正确输出其回文的可能性？

在字符{A, C, G, T}组成的DNA序列中，A和T、C和G是互补对。判断一个DNA序列中是否存在互补回文串（例如，ATCATGAT的补串是TAGTACTA，与原串形成互补回文串）。下面DNA序列中存在互补回文串的是：（多选） In the DNA sequences consisting of character {A, C, G, T}, A and T, C and G are complementary pairs. Judging whether there is a complementary palindrome sequence in a DNA sequence (e.g., ATCATGAT’s complement strings is TAGTACTA, it is complementary palindrome sequence with the original sequence). Which of the following DNA sequences have complementary palindrome string? （There are more than one answers.）

A、CTGATCAG

B、AATTAATT

C、TGCAACGT

D、CATGGTAC

E、GTACGTAC

F、AGCTAGCT
