문제

DNA란 어떤 유전물질을 구성하는 분자이다. 이 DNA는 서로 다른 4가지의 뉴클레오티드로 이루어져 있다(Adenine, Thymine, Guanine, Cytosine). 우리는 어떤 DNA의 물질을 표현할 때, 이 DNA를 이루는 뉴클레오티드의 첫글자를 따서 표현한다. 만약에 Thymine-Adenine-Adenine-Cytosine-Thymine-Guanine-Cytosine-Cytosine-Guanine-Adenine-Thymine로 이루어진 DNA가 있다고 하면, “TAACTGCCGAT”로 표현할 수 있다. 그리고 Hamming Distance란 길이가 같은 두 DNA가 있을 때, 두 DNA의 차이를 표현하는 것이다. 만약에 “AGCAT"와 ”GGAAT"는 첫 번째 글자와 세 번째 글자가 다르므로 Hamming Distance는 2이다.

우리가 할 일은 다음과 같다. n개의 길이가 같은 DNA가 주어져 있을 때(이 DNA를 a1a2a3a4...이라고 하자) Hamming Distance의 합이 가장 작은 DNA s를 구하는 것이다. 즉, s와 a1의 Hamming Distance + s와 a2의 Hamming Distance + s와 a3의 Hamming Distance ... 의 합이 최소가 된다는 의미이다.

입력

It consists of four different nucleotides, namely Adenine, Thymine, Guanine, and Cytosine as shown in Figure 1. If we represent a nucleotide by its initial character, a DNA strand can be regarded as a long string (sequence of characters) consisting of the four characters A, T, G, and C. For example, assume we are given some part of a DNA strand which is composed of the following sequence of nucleotides: &ldquo;Thymine-Adenine-Adenine-Cytosine-Thymine-Guanine-Cytosine-Cytosine-Guanine-Adenine-Thymine&rdquo; Then we can represent the above DNA strand with the string &ldquo;TAACTGCCGAT.&rdquo;<\/p>\r\n\r\n<p>The biologist Prof. Ahn found that a gene X commonly exists in the DNA strands of five different kinds of animals, namely dogs, cats, horses, cows, and monkeys. He also discovered that the DNA sequences of the gene X from each animal were very alike. See Figure 2.&nbsp;<\/p>\r\n\r\n<p><img alt=\"\" src=\"\/upload\/images\/dnab2.png\" style=\"height:169px; width:362px\" \/><\/p>\r\n\r\n<p>Prof. Ahn thought that humans might also have the gene X and decided to search for the DNA sequence of X in human DNA. However, before searching, he should define a representative DNA sequence of gene X because its sequences are not exactly the same in the DNA of the five animals. He decided to use the Hamming distance to define the representative sequence.<\/p>\r\n\r\n<p>The Hamming distance is the number of different characters at each position from two strings of equal length. For example, assume we are given the two strings &ldquo;AGCAT&rdquo; and &ldquo;GGAAT.&rdquo; The Hamming distance of these two strings is 2 because the 1st and the 3rd characters of the two strings are different. Using the Hamming distance, we can define a representative string for a set of multiple strings of equal length. Given a set of strings {s1, ..., sm} of length n, the consensus error between a string y of length n and the set S is the sum of the Hamming distances between y and each si in S. If the consensus error between is y and S is the minimum among all possible strings of length n, is called a consensus string of . For example, given the three strings &ldquo;AGCAT&rdquo;, &ldquo;AGACT&rdquo;, and &ldquo;GGAAT&rdquo;, the consensus string of the given strings is &ldquo;AGAAT&rdquo; because the sum of the Hamming distances between &ldquo;AGAAT&rdquo; and the three strings is 3 which is minimal. (In this case, the consensus string is unique, but in general, there can be more than one consensus string.) We use the consensus string as a representative of the DNA sequence. For the example of Figure 2 above, a consensus string of gene X is &ldquo;GCAAATGGCTGTGCA&rdquo; and the consensus error is 7.&nbsp;<\/p>\r\n","input":"<p>Your program is to read from standard input.
