In our daily life we often use 233 to express our feelings. Actually, we may say 2333, 23333, or 233333 ... in the same meaning. And here is the question: Suppose we have a matrix called 233 matrix. In the first line, it would be 233, 2333, 23333... Besides, in 233 matrix, we got ai,j=ai1,j+ai,j1a_{i,j} = a_{i-1,j} +a_{i,j-1}ai,j=ai1,j+ai,j1. Now you have known a1,0,a2,0,...,an,0, could you tell me an,m in the 233 matrix?

Besides, in 233 matrix, we got ai,j=ai−1,j+ai,j−1a_{i,j} = a_{i-1,j} +a_{i,j-1}ai,j=ai−1,j+ai,j−1(i,j≠0)( i,j not= 0)(i,j=0). Now you have known a1,0,a2,0,...,an,0, could you tell me an,m in the 233 matrix?
