Write your MATLAB scripts for the following problems. 1. (30%) Assuming that Pn is a sequence "look and say" the digits of the previous sequence, and Sn is the sum of sequence P. For example, P = {1}, S = 1, P = {1,1}, S = 2, P = {2,1}, S = 3, P ={1,2,1,1, S = 5, P ={1,1,1,2,2,1), S, = 8, P = {3,1,2,2,1,1), S = 10. P reads P as "one 1" and S is 2, P, reads P as "two 1" and S, is 3, P, reads P, as "one 2, and one 1" and S, is 5, and P, reads P as "one 1, one 2, and two 1" and S, is 8, and so on. (a) Provide your pseudocode. (b) Please find S20 and S40-
