1. 문제 We define a palindrome to be a sequence of characters that reads the same backward as it does forward. For example, “tacocat” and “12221” are palindromes, but, “tacocats” and “8675” are not. We define a subsequence to be a sequence formed by copying a contiguous section of elements from sequence and deleting 0 or more characters from it.
