Question

You are given a 3x3 matrix, with the first row and the first column
filled with positive integers. The remaining entries are 0. You have
to "complete" the matrix in the following way.

Starting from the top left unfilled element [i][j], we ensure that

a[i][j] = a[i-1][j] + a[i][j-1]

where a[i-1][j] and a[i][j-1] are elements which were already filled.

Output a[2][2].
