The problem of electing a leader in a city with n people can be solved using the algorithm of leader election. In this algorithm, each person in the city randomly selects another person and compares their own ID number with the ID number of the person they have selected.
If the ID number of the selected person is smaller than their own ID number, they drop out of the election. The remaining people repeat this process until only one person is left, who is declared the leader. To derive a recurrence for the average number L(n) of rounds needed to elect a leader, we can consider the probability that a person is eliminated in each round. Let p(n) be the probability that a person is eliminated in one round when there are n people. Then, the probability that a person is not eliminated in one round is 1 - p(n), and the probability that they survive k rounds is (1 - p(n))^k. Therefore, the probability that they are eliminated after k rounds is 1 - (1 - p(n))^k.
The expected number of rounds needed to elect a leader can be obtained by summing over all possible values of k, weighted by the probability of surviving k rounds and then being eliminated in the (k+1)th round. This gives the recurrence: L(n) = 1 + ∑_{k=0}^{n-2} (1 - (1 - p(n))^k) L(n-1) Using the probability of elimination in one round, p(n) = 1/n, we can simplify this recurrence to: L(n) = 1 + ∑_{k=0}^{n-2} ((n-1)/n)^k L(n-1) To compute and plot L(n) vs n, we can use this recurrence and start with the base case L(1) = 0. The resulting plot shows that the average number of rounds needed to elect a leader increases logarithmically with the size of the city.

The Great Firewall of China could build a system to block access to selected hosts on the internet using DNS by creating a blacklist of specific domain names or IP addresses that they want to block.
They would then intercept all DNS requests from users within China and compare them to the blacklist. If the requested domain or IP address is on the blacklist, the Firewall would respond with a fake DNS record that redirects the user to a dead end or a blocked page. However, if the requested domain or IP address is not on the blacklist, the Firewall would let the DNS request pass through to its intended destination, allowing all other traffic to flow freely.

An element in an array is accessed in memory. The pre-loading of other data in that array is an example of what kind of locality
An element in an array being accessed in memory, followed by the pre-loading of other data in that array, is an example of spatial locality
The pre-loading of other data in an array is an example of spatial locality, which is a type of locality in computer memory access patterns. Spatial locality refers to the tendency of a computer program to access data that is close in memory to data that has already been accessed. This is because modern computer systems often use a memory hierarchy where data is stored in different levels of cache, with faster and smaller caches closer to the processor.
When an element in an array is accessed in memory, the pre-loading of other data in that array can take advantage of spatial locality. For example, if an array is stored in memory as consecutive blocks of data, accessing one element will also load the adjacent elements into the cache. If the program then accesses these adjacent elements in the near future, they will be immediately available in the cache, resulting in faster memory access times and improved performance.
Spatial locality is an important concept in computer architecture and programming, as it can greatly impact the performance of programs that rely on accessing large amounts of data. By optimizing memory access patterns to take advantage of spatial locality, programmers can improve the speed and efficiency of their programs.

The Pigeonhole Principle states that if n items are put into m containers, with n > m, then at least one container must contain more than one item. In this case, there are 31 possible subsets, and if we output subsets randomly, there is no way to guarantee that any two subsets will be the same. Therefore, we need to output at least 32 subsets to guarantee that one subset is outputted twice. Therefore, the minimum number of times the program must be executed to guarantee that one subset is outputted twice is 33 times.

The order of growth for the depth of recursion associated with the text's recursive factorial (returns N!) method is:___________
a) O(N)
b) O(log2N).
c) O(1).
d) O(N^2)
The order of growth for the depth of recursion associated with the text's recursive factorial method is O(N).
In the recursive factorial method, the base case is when N equals 1, and the recursive case is when N is greater than 1. Each recursive call decrements N by 1 until it reaches the base case. Therefore, the number of recursive calls is equal to N-1, which means the depth of the recursion is N-1.Since the depth of recursion is directly proportional to N, the order growth for the depth of recursion is O(N). This means that as N grows, the depth of recursion grows linearly. In other words, if N doubles, the depth of recursion doubles as well.It's worth noting that the time complexity of the recursive factorial method is also O(N), as each recursive call takes constant time and there are N recursive calls in total.

; 2 parameters passed ; string1 ghost0 ("ghost") AT ADDRESS 1000 (goes into the ESI register) ; string2 ghostly0 ("ghostly") AT ADDRESS 2000 (goes into the EDI register) ; remember, C++ delineates the end of a string by adding zero _Task1 proc _asm Mov bx,0 ; set return result to failed mov esi, DWORD PTR [esp + 4] ; this is taking a passed pointer off the stack mov edi, DWORD PTR [esp + 8] ; this is taking a passed pointer off the stack L1: mov al, [esi] ; when the register is in square brackets, you mov ah, [edi] ; are asking for the contents of that address cmp al, 0 jne L2 cmp ah, 0 jne L2 mov bx,1 jmp L3 L2: inc esi ; INC works because it is only increasing 1 byte inc edi cmp al, ah je L1 L3: ret _Task1 endp ;WHAT DOES THIS TASK DO? End
This task is a comparison function written in assembly language that takes in two parameters, string1 and string2, passed as pointers. The function first sets the return result to failed by assigning 0 to the bx register.
Then, it retrieves the addresses of string1 and string2 from the stack and assigns them to esi and edi registers respectively. The function then enters a loop labeled L1, where it compares the contents of the memory location pointed to by esi and edi registers with zero. If both registers contain zero, it means the end of strings has been reached and the function assigns 1 to bx register and jumps to L3. If either register contains non-zero value, it means the strings are not equal and the function increments the pointers to move to the next character and compares them again. If the characters are not equal, the function assigns 0 to bx and jumps to L3. Once the loop ends, the function returns the value of bx. In summary, this task compares two strings and returns 1 if they are equal, and 0 if they are not.
This task, written in assembly language, compares two strings (string1 and string2) and determines if they are equal or not. The two parameters passed to this task are the addresses of the two strings: string1 "ghost" at address 1000 and string2 "ghostly" at address 2000. In C++, strings are delineated by a null character (zero) at the end.
The task initializes the return result to failed (0) and retrieves the passed pointers for the two strings from the stack. It then compares the characters of the two strings one by one. If the characters at the current positions are equal, the task increments the pointers to check the next characters. If the task encounters a null character for both strings, it means the strings are equal, and the return result is set to success (1). The task ends when a difference is found or when the end of the strings is reached, returning the result.
