문제

1979년 댄 브리클린과 밥 프랜스턴은 첫 번째 스프레드시트 어플리케이션인 VisiCalc를 만들었다. 이 프로그램은 매우 크게 성공했으며, 애플 II 컴퓨터의 필수 앱이었다. 오늘날 스프레드시트는 대다수의 데스크탑 컴퓨터에 설치되어져 있다.

스프레드시트에 핵심이 되는 아이디어는 매우 간단하지만 강력하다. 스프레드시트는 표로 이루어져 있으며, 표의 각 칸은 정수나 수식으로 이루어져있다. 수식은 다른 칸에 쓰여 있는 값을 기반으로 계산된다.

오늘은 매우 간단한 스프레드시트 앱을 만드려고 한다. 스프레드시트의 각 칸은 정수나 수식으로 이루어져 있으며, 수식은 합만 지원한다. 스프레드시트의 각 칸에 적힌 정수나 수식이 주어졌을 때, 수식을 모두 계산해내는 프로그램을 작성하시오.

스프레드시트의 각 칸은 아래와 같이 번호가 매겨져 있다.

 A1    B1     C1     D1     E1     F1     ...    
 A2    B2     C2     D2     E2     F2     ...    
 A3    B3     C3     D3     E3     F3     ...    
 A4    B4     C4     D4     E4     F4     ...    
 A5    B5     C5     D5     E5     F5     ...    
 A6    B6     C6     D6     E6     F6     ...    
 ...   ...    ...    ...    ...    ...    ...    

입력

입력의 첫째 줄에는 테스트 케이스의 개수가 주어진다.

각 테스트 케이스의 첫째 줄에는 스프레드시트의 열의 개수 M과 행의 개수 N이 주어진다. 다음 줄부터 N개의 줄에는 스프레드시트의 내용이 주어진다. 각 행은 열의 정보가 주어지며, 공백으로 구분되어져 있다.

각각의 칸은 정수가 적혀있거나, 수식이 적혀있다. 수식은 =로 시작되며, 그 뒤에 칸의 이름이 +로 구분되어져서 주어진다. 수식의 값은 각 칸에 쓰여 있는 칸에 적혀져있는 수식을 모두 더한 값이다. 수식은 수식이 적혀있는 칸을 가리킬 수 있으며, 수식에는 공백이 주어지지 않는다.

가리키는 관계가 사이클을 이루는 경우는 없기 때문에, 항상 수식을 계산할 수 있다.

칸의 이름 중에서 열은 1부터 999까지의 정수로 나타내며, 행은 A, B, C, ..., Z, AA, AB, AC, ..., AZ, BA, ..., BZ, CA, ... ZZ, AAA, AAB, AAC, ... AAZ, ABA, ..., ABZ, ACA, ..., ZZZ 로 문자가 매겨져 있다. 가장 왼쪽 위의 칸 번호는 A1이다.

각 칸에 적혀있는 수는 절대값이 100,000보다 작거나 같은 정수이며, 수식의 값이 231-1을 넘어가는 경우는 없다.

출력

각각의 테스트 케이스마다, 수식을 모두 계산해서 출력한다.

It became a huge success and, at that time, was the killer application for the Apple II computers. Today, spreadsheets are found on most desktop computers.<\/p>\r\n\r\n<p>The idea behind spreadsheets is very simple, though powerful. A spreadsheet consists of a table where each cell contains either a number or a formula. A formula can compute an expression that depends on the values of other cells. Text and graphics can be added for presentation purposes.<\/p>\r\n\r\n<p>You are to write a very simple spreadsheet application. Your program should accept several spreadsheets. Each cell of the spreadsheet contains either a numeric value (integers only) or a formula, which only support sums. After having computed the values of all formulas, your program should output the resulting spreadsheet where all formulas have been replaced by their value.<\/p>\r\n\r\n<pre>\r\n A1    B1     C1     D1     E1     F1     ...    \r\n A2    B2     C2     D2     E2     F2     ...    \r\n A3    B3     C3     D3     E3     F3     ...    \r\n A4    B4     C4     D4     E4     F4     ...    \r\n A5    B5     C5     D5     E5     F5     ...    \r\n A6    B6     C6     D6     E6     F6     ...    \r\n ...   ...    ...    ...    ...    ...    ...    \r\n<\/pre>\r\n","input":"<p>The first line of the input file contains the number of spreadsheets to follow. A spreadsheet starts with a line consisting of two integer numbers, separated by a space, giving the number of columns and rows. The following lines of the spreadsheet each contain a row. A row consists of the cells of that row, separated by a single space.<\/p>\r\n\r\n<p>A cell consists either of a numeric integer value or of a formula. A formula starts with an equal sign (=). After that, one or more cell names follow, separated by plus signs (+). The value of such a formula is the sum of all values found in the referenced cells. These cells may again contain a formula. There are no spaces within a formula.<\/p>\r\n\r\n<p>You may safely assume that there are no cyclic dependencies between cells. So each spreadsheet can be fully computed.<\/p>\r\n\r\n<p>The name of a cell consists of one to three letters for the column followed by a number between 1 and 999 (including) for the row. The letters for the column form the following series: A, B, C, ..., Z, AA, AB, AC, ..., AZ, BA, ..., BZ, CA, ... ZZ, AAA, AAB, AAC, ... AAZ, ABA, ..., ABZ, ACA, ..., ZZZ.
