Assume (for simplicity in this exercise) that only one tuple fits in a block and memory holds at most three blocks. Show the runs created on each pass of the sort-merge algorithm when applied to sort the following tuples on the first attribute: (kangaroo, 17), (wallaby, 21), (emu, 1), (wombat, 13), (platypus, 3), (lion, 8), (warthog, 4), (zebra, 11), (meerkat, 6), (hyena, 9), (hornbill, 2), (baboon, 12).
Consider a list of data components L[0:5] = 23, 14, 98, 45, 67, and 53. Let's look for the K = 53 key. Naturally, the search moves down the list, comparing key K with each element until it discovers it as the final element in the list. When looking for the key K = 110, the search moves forward but eventually drops off the list, making it a failed search. Write the algorithmic steps for both sorted and unordered linear searches, along with the times involved.
Observe the following two Sequential Search and Binary Search algorithms in the image. Perform a comparative analysis of the Sequential Search and Binary Search algorithms in terms of the number of basic operations executed by the two algorithms. A. Calculate and analyze the time complexity T(n) and the efficiency class of the two search algorithms in the worst case. B. Write an example case by writing down the elements for different data sizes, for example n=4, 8, ... Please specify the elements of table A and the data you are looking for, x. Write an illustration of the comparison process for every n to confirm the complexity of the algorithm in point a). C. Describe your opinion regarding the comparative analysis of the efficiency of the two algorithms! Please solve subparts A,B,C in 60 minutes ASAP can u get thank u
The size of the intersection divided by the size of the union is used to determine how similar two papers are (each having unique words). For instance, the similarity between 1, 5, 3 and 1, 7, 2, 3 is 0, 4, as the intersection has size, if the documents are made up of integers.the union has a size of 2, andWe have a large collection of documents (each with a unique value and a corresponding ID), where the similarity is deemed to be "sparse":This means that there is a high likelihood of resemblance between any two randomly chosen papers. O. Create an algorithm that provides a list of document ID pairings together with the corresponding similarity.Only the pairings with similarity larger than 0 should be printed. Documents that are empty should not
Correct answer will be upvoted else Multiple Downvoted. Don't submit random answer. Computer science. You are given an integer k and n particular focuses with integer facilitates on the Euclidean plane, the I-th point has arranges (xi,yi). Consider a rundown of all the n(n−1)2 sets of focuses ((xi,yi),(xj,yj)) (1≤i<j≤n). For each such pair, work out the separation from the line through these two focuses to the beginning (0,0). You will likely work out the k-th most modest number among these distances. Input The principal line contains two integers n, k (2≤n≤105, 1≤k≤n(n−1)2). The I-th of the following n lines contains two integers xi and yi (−104≤xi,yi≤104) — the directions of the I-th point. It is ensured that all given focuses are pairwise particular. Output You should output one number — the k-th littlest separation from the beginning. Your answer is considered right if its outright or relative blunder doesn't surpass 10−6. Officially, let your answer be…
Note: Your solution should have O(n) time complexity, where n is the number of elements in l, and O(1) additional space complexity, since this is what you would be asked to accomplish in an interview. Given a linked list l, reverse its nodes k at a time and return the modified list. k is a positive integer that is less than or equal to the length of l. If the number of nodes in the linked list is not a multiple of k, then the nodes that are left out at the end should remain as-is. You may not alter the values in the nodes - only the nodes themselves can be changed.

Consider a open bucket hash table and closed bucket hash table in which the keys are student identifiers (strings of 6 digits). Assume the following number of buckets and hash function: m = 100; hash(id) = first two digits of id #. Starting with an empty hash table, show the effect of successively adding the following student identifiers: 000014, 990021, 990019, 970036, 000015, 970012, 970023. Use following function as second hash function hash(id) = last digit of id # Show the effect of deleting 000014 from the hash table. (Java Programming DSA)
Correct answer will be upvoted else downvoted. table can be addressed as a square shape with stature h and width w, isolated into h×w cells. Let (i,j) signify the cell in the I-th line and the j-th segment of the square shape (1≤i≤h; 1≤j≤w). Into every cell of the table you can either put a plate or keep it unfilled. As every visitor must be situated close to their plate, you can just put plates on the edge of the table — into the first or the last line of the square shape, or into the first or the last segment. Officially, for every cell (i,j) you put a plate into, no less than one of the accompanying conditions should be fulfilled: i=1, i=h, j=1, j=w. To make the visitors agreeable, no two plates should be placed into cells that have a typical side or corner. All in all, if cell (i,j) contains a plate, you can't place plates into cells (i−1,j), (i,j−1), (i+1,j), (i,j+1), (i−1,j−1), (i−1,j+1), (i+1,j−1), (i+1,j+1). Put whatever number plates on the table as could be…
I NEED HELP IN THIS QUESTION OF DATA STRUCUTRE AND ALGO ASAP Consider the following scenario/assumptions: A hash table can store at most 11 elements. Indices are numbered from 0 to 10. It is currently empty (no elements yet). The hashing function is defined as H(k) = k % 11 The collision resolution technique is Linear Probing. Insert the following keys in the hash table in the sequence that they appear below: 172458 282459 392458 502461 612458 722463 832458 942465 1052458 1162467 Write on a piece of paper the contents of the resulting has table after inserting these keys. The table should contain 10 elements, with only one address that is left open, i.e., it is not occupied by any key
