- A grid needs a system for numbering the tiles in order to allow random-access lookup.For instance, the rows and columns of a square grid provide a natural numbering for the tiles. Create plans for hexagonal and triangular grids. Create a rule for identifying the neighbourhood (i.e., nearby tiles) of a certain tile in the grid using the numbering scheme. For instance, the neighbourhood of tile I j in a four-connected square grid with indices of I for rows and j for columns may be described as neighbourhood(i, j) = I 1, j, I j 1.2022-02-14 20:52:35 Write the primitive counting results for your 40 sheep: 40= For example, the answer for "14" would be (1,1,1,0), meaning that the first division of sheep had none left over, but every other division of sheep had a leftover sheep.

- To start compute φ, the number of ways that 3 ☐'s could be inserted into a genetic string s, where |s| = 10, and ☐ represents a space (' ') φ = x + y + z, where• x = the number of possibilities for inserting '☐☐☐'• y = y₁*y₂, where y₁ = the number of possibilties for inserting '☐☐' at any position p, and y₂ = the number of possibilites for inserting the remaining '☐' at position q ≠ p.• z = the number of possibilities for inserting the 3 ☐'s at 3 different positionsLet B be the set of all binary strings of length 8. {“00000000”, “00000001”, … “11111110”, “11111111”} How many elements of B have no adjacent digits with the same value? How many elements of B are palindromes? How many elements of B contain two or more 0s?Modeling the spread of a virus like COVID-19 using recursion. Let N = total population (assumed constant, disregarding deaths, births, immigration, and emigration). S n = number who are susceptible to the disease at time n (n is in weeks). I n = number who are infected (and contagious) at time n. R n = number who are recovered (and not contagiuous) at time n. The total population is divided between these three groups: N = S n + I n + R n There are several hidden assumptions here that may or may not apply to COVID-19, such as a recovered person is assumed to not be able to get the disease a second time, at least within the time window being examined. On week 0 (the start), you assume a certain small number of people have the infection (just to get things going). Everyone else is initially susceptible, and no one is recovered. There are two constants of interest: Let period = time period that it takes for an infected person to recover (recover meaning they become not infectious to…
- The parity function is a very simple hash function producing a one-bit digest, which is 0 if the number of bits in the message is even and 1 if it is odd. Consider a communication system that uses 7 bits out of every byte to transmit data, and reserves the 8th bit (the one on the right) to transmit the parity of the other seven bits, for purposes of error checking. Below is the binary representation of some bytes that were transmitted using this system. For each one, tell whether there is a reason to suspect an error in transmission, giving the reason for your answer. 10110011 11101111 10101100 00110011Log base 10 of x + log base 10 of x+3 =1 x?Suppose Alice computes the Secret suffix MAC (page 322: secret suffix MAC(x) = h(x || key)) for the message ”AM” with key “G” that both Alice and Bob know. The hash function that is used is h(x1x2x3)= g(g(x1 XOR x2) XOR x3 ) where each xi is a character represented as 8 bits, and g(x) is a 8-bit string that is equal to the complement of bits in x. For example, g(10110011) = 01001100. The MAC is 8 bits. (8-bit ASCII representation of the characters is given below.) What is the Secret suffix MAC computed by Alice? Show the MAC as the single character. What information is sent by Alice to Bob.
