Let Ax = {a,b,...,z,—}, |Ax| = 27, denote alpahabet of letters in English text where - represents the space character between words. Let Px = {P₁, P2,..., P27} denote the probability of letters. 1) Estimate pi, by parsing the text "All Systems Red' by Martha Wells. To do this you have to parse the letters in the book and form a character vector x = = [1, 2,..., TN] where N is the number of letters in the book. (Turn all uppercase letters into lowercases and ignore the characters that are not in Ax). You may use Matlab or Python. Then you can estimate p; by its frequency in the text #(x₁ = ai) N where #(i = a;) denotes the number of times ï¿ = a¿ in x. Pi = (1)

Correct answer will be upvoted else Multiple Downvoted. Computer science. The j-th companion can be set before the I-th companion on the photograph if his square shape is lower and smaller than the square shape of the I-th companion. Officially, somewhere around one of the accompanying conditions should be satisfied: hj<hi and wj<wi (the two companions are standing or both are lying); wj<hi and hj<wi (one of the companions is standing and the other is lying). For instance, on the off chance that n=3, h=[3,5,3] and w=[4,4,3]: the main companion can be set before the second: w1<h2 and h1<w2 (one of the them is standing and the other one is lying); the third companion can be put before the second: h3<h2 and w3<w2 (the two companions are standing or both are lying). In different cases, the individual in the closer view will cover the individual behind the scenes. Help Polycarp for every I find any j, with the end goal that the j-th…
