4) We want to develop an algorithm to solve a problem. To do that, we use a recursive design approach and here is the final formulation of the problem: P[i, j] P[i-1,j] + P[i,j-1]+P[i - 1,j-1] P[0,0] = 0 P[0,1] = P[1,0] = 1 Write a dynamic programming pseudo-code to implement this idea. Imagine that i and j are in the range of 1 and n. (15 pts)
