문제

음악에는 C, D, E, F, G, A, B 이렇게 7개의 음정이 있다. 그리고 3개의 음악이 주어질 것이다. 아래의 표를 보면

다음 3개의 음악은 값이 7이 되는 것을 알 수 있다. (음악의 길이가 다른 관계로 3번째 음악은 '&'(공백)이 삽입되었다.)

값을 정하는 방법은 ‘&’를 제외한 7개의 음정 중에 3개의 음악에도 동시에 한 음을 연주하면 3점이고 동시에 2개를 연주하면 1점이고 그렇지 않으면 0점이다. ('&'이 두개라서 1점이 되지는 않는다.)

같은 세 음악임에도 불구하고 중간 중간에 '&'을 삽입함으로써 값이 25로 증가 하였다.
‘&’이 포함되지 않은 세 개의 음악을 입력받아 이것이 값이 최대가 되도록 ‘&’를 삽입하여 그 때의 최대 값을 출력하는 프로그램을 작성하시오.

또 한 가지!!

이와 같이 한 음악에서 연속해서 '&'를 두 번 이상(두 번 포함) 연주하게 해서는 안 된다.

'&'를 연속해서 두 번 이상 쓰지 않고 위와 같은 정렬을 할 수 조차 없을때는 -1을 출력한다.
Music1 : CGCC
Music2 : C
Music3 : CC

다음 3개의 음악은 길이의 차이가 너무 많이 나서 길이를 맞추려면 '&'를 두개 이상 써야 되므로 값이 -1이다.

입력

한 줄에 한 음악씩 3개의 음악이 주어진다. 음악의 최대길이는 100을 넘지 않는다.

출력

첫째 줄에 가장 좋게 배치 했을 때의 값을 출력한다.

We want to arrange new polyphonic music with three different monophonic music scores of arbitrary length. Each monophonic music score has only 7 tones, C(do), D(re), E(mi), F(fa), G(sol), A(la), B(si) with the same interval.&nbsp;<\/p>\r\n\r\n<p>You can see polyphonic music X with three monophonic music scores (Music1, Music2, Music3) in Figure 1. Note that the lengths of Music1, Music2, and Music3 are 12, 12, 11, respectively. &lsquo;&amp;&rsquo; is the symbol of a pause and means that no tone is played in that position. Music X is the same as playing 3 different monophonic music scores (Music1, 2, 3) simultaneously. The tones in each column of Figure-1 denote a set of tones to be played simultaneously in polyphonic music.&nbsp;<\/p>\r\n\r\n<p><img alt=\"\" src=\"\/upload\/images\/uni.png\" style=\"height:133px; width:487px\" \/><\/p>\r\n\r\n<p>Let us define &ldquo;unison&rdquo; in this problem. A unison is an instance where the same tones are played simultaneously in a score. Thus, column1 = { A, F, A } and column2 = {C, C, F} are not unisons, so the music score X has only three unisons: column6={B, B, B}, column10 = {D, D, D}, and column12 = {A, A, &amp;} . Formally, a column M = {x, y, z} is a unison, if M has three of the same tones or two of the same tones plus &amp;. If x = y = z &ne; &lsquo;&amp;&rsquo;, then the weight of the unison is 3. If M has two of the same tones and a single &lsquo;&amp;&rsquo;, then the weight of the column is 1. The sum of all unisons in a score is called the total unison weight. The following table shows the unison weight for each tone set.&nbsp;<\/p>\r\n\r\n<p><img alt=\"\" src=\"\/upload\/images\/uni2.png\" style=\"height:265px; width:326px\" \/><\/p>\r\n\r\n<p>The unison weight of score X in Figure-1 is 3 + 3 + 1 = 7.

One important constraint on inserting &lsquo;&amp;&rsquo; is that you should not insert more than one consecutive &amp; in a music score. See Figure 3 for this constraint. Also, you are not allowed to modify the tones (melody) or to change the sequence of tones. Keep in mind that your arrangement can only insert &amp;&rsquo;s separately to get a maximal unison.&nbsp;<\/p>\r\n\r\n<p>Write a program that finds the maximal unison weight by using an optimal arrangement.&nbsp;<\/p>\r\n\r\n<p><img alt=\"\" src=\"\/upload\/images\/uni4.png\" style=\"height:120px; width:494px\" \/><\/p>\r\n","input":"<p>The input consists of T test cases.
