Nikolai assigned students the task of creating a RACI matrix for a project during management lectures. This is a responsibility assignment matrix that lists all stakeholders of the project and their levels of involvement in different tasks. The levels are denoted by the letters "`R<\/code>", "A<\/code>", "C<\/code>", and "I<\/code>". If there is no involvement, "-<\/code>" is used. The levels of involvement have the following meaning:<\/p>`
R<\/code> (Responsible<\/em>): performs the task (if they are absent, then Accountable<\/em> performs the whole task)<\/li> A<\/code> (Accountable<\/em>): accepts the task from Responsible<\/em>; for each task, there must be exactly one instance of this level of involvement, unlike the other levels, of which there can be any number<\/li> C<\/code> (Consulted<\/em>): provides consultation during the execution of the task<\/li> I<\/code> (Informed<\/em>): receives information about the progress of the task<\/li> <\/ul> Help the students verify the correctness of the matrix.<\/p> 입력<\/h2> The first line contains two integers $n<\/mi><\/mrow>n<\/math><\/span><\/span> n<\/span><\/span><\/span><\/span> and m<\/mi><\/mrow>m<\/math><\/span><\/span> m<\/span><\/span><\/span><\/span>: the number of rows and columns of the RACI matrix (1<\/mn>\leq<\/mo>n<\/mi>,<\/mo>m<\/mi>\leq<\/mo>100<\/mn><\/mrow>1 \le n, m \le 100<\/math><\/span><\/span> 1<\/span> <\/span> \leq<\/span> <\/span><\/span> <\/span> n<\/span>,<\/span> <\/span> m<\/span> <\/span> \leq<\/span> <\/span><\/span> <\/span> 100<\/span><\/span><\/span><\/span>).<\/p> Next,$
