Consider the following modification to procedure MESH SEARCH. As usual, P(l, 1) receives the input. During the unfolding stage processor P(i,j) can send data simultaneously to P(i + 1, j) and P(i, j + 1). When the input reaches P(n1 / 2, n1 /2), this processor can compute the final answer and produce it as output (i.e., there is no folding stage). Describe the modified procedure formally and analyze its running time.
