One of the downsides of a pure interpretation implementation is that it is less compact from a space perspective.

1.  Computing lookahead sets is more complex when a rule contains ……… a. multiple alternatives b. token reference c. empty alternative d. all the above e. none of these are appropriate answers

(A) The first task is to create a scanner for python language. The scanner should have the following features. • Skip over white spaces. • Recognize all keywords and return the correct token. The scanner implemented for c in the slides can be used as a reference. (B) The second task is to implement a parser of your choice. You can choose any top down or bottom up parser.

Write a function with the interface doRandomWalk(nstep,startPosition), that takes the number of steps nstep for a random walk and the startPosition of the random walk on a straight line, and returns the location of the final step of the random walker. Problem Part B Now, write another function with the interface simulateRandomWalk(nsim,nstep,startPosition) that simulates nsim number of random-walks, each of which contains nstep steps and starts at startPosition. Then, this function calls doRandomWalk() repeatedly for nsim times and finally returns a vector of size nsimcontaining final locations of all of the nsim simulated random-walks. Problem Part C Now write a script that plots the output of simulateRandomWalk() for nsimnstepstartPosition===1000010−10 The resulting plot should look like the following,   How do you interpret this result? How can uniformly-distributed random final steps end up having a Gaussian bell-shape distribution.

Your task for this lab is to write a program in any language you like(c language) to determine the number of rabbits we would have in 24 months.  You can check the validity and correctness of your program by testing the count at month 3, 4, and 5 to see if it matches the pair count in the diagram.

Python Need help with code A rule has three parts: •name –a simple name for the rule (e.g., up, left, down, right) •precondition function –a Boolean function that accepts a state and returns true if the rule is applicable to state •action function –a function that accepts a state and returns the successor state obtained by applying the rule. You can use these rules to implement functions such as applicable-rule, which returns a list of the rules applicable to a given state, and successor-state, which returns the successor state for a given state and rule. Question: Encode the rules for the sliding-tile puzzle. Remember that it is easiest to consider moving the empty space up, left, down, or right. Using these rules, write routines to determine the rules applicable to a state and the successor state given a state and rule to apply. Note that you could implement these as iterators or have them return lists (or vectors) or rules and states.

Define pseudoinstruction.

Please help me with this in c++. A simulation creates a model of a real-world situation, allowing us to introduce a variety of conditions and observe their effects. For instance, a flight simulator challenges a pilot to respond to varying conditions and measures how well the pilot responds. Simulation is frequently used to measure current business practices, such as the number of checkout lines in a grocery store or the number of tellers in a bank, so that management can determine the fewest number of employees required to meet customer needs. Airlines have been experimenting with different boarding procedures to shorten the entire boarding time, keep the flights on-time, reduce aisle congestion, and make the experience more pleasant for passengers and crew. A late-departing flight can cause a domino effect: the departure gate is tied up and cannot be used by other landing or departing flights, passengers on board the late flight may miss connecting flights and require rebooking and…

Finish the 2 "TODO" in the ASM Language! A palindrome is a word that is spelled the same way forwards and backwards. For example, "radar", "racecar", "civic", "kayak", and "madam" are all palindromes. The definition can be extended to phrases and sentences when ignore case and punctuation, but for this exercise we will stick to a single word. The starter code provided uses the C library functions printf and scanf to prompt for an input a word. The word that is entered from the keyboard is a null-terminated string placed in the byte array at address buf. There are also two output strings provided at addresses str_is_palindrome and str_is_not_palindrome. The starter code provided simply outputs the string at str_is_not_palindrome. The code contains two TODO comments... At the first TODO comment, the byte array at buf is filled with input from the keyboard. This input is a null-terminated character string (i.e. the array contains the characters entered on the keyboard, followed by ASCII…
