Stack operations

A stack is a linear data structure that follows certain order to perform the operation; the order will be LIFO (Last In First Out) data structure. In the stack data structure elements/items are removed and added only from the top. The topmost stack item/element is pointed by the top pointer and the element which is added to the stack first will get deleted at the last.

Question

06. Assume that you have built a dense primary
B+ tree index on a heap file containing 20,000
records. The key field for this B+ tree index is
a 40 byte string and it is a candidate key.
Pointers (i.e. record ids and page ids) are (at
most) 10 byte values. The size of one disk
page is 1,000 bytes . The index was built in a
bottom-up fashion using the bulk-loading
algorithm, and the nodes were filled up as
much as possible. Then there are
number levels in the tree.

Make a list of 500 three-digit numbers using a random number generator. Make a FILE with a list of the 500 numbers in order. Create artificial storage blocks on the sequential list, each of which can hold no more than 10 digits. The highest key in each storage block is recorded together with the storage block's address in an index called INDX that is opened over the sequential list FILE. Indexed Sequential search should be used to search for keys K in FILE. Compare how many comparisons the search made to how many the sequential search made using the same set of keys. Include an index over the index INDX in the extension of the implementation.
Program 12_2.java Write a program that creates a small (6-10) array of ints. Display your array elements, all on one line, using a foreach loop. In a try block, prompt the user to enter an index for the array and attempt to print the element with that index. Follow the try block with two catch blocks; one that detects an index out of bounds, and another that catches other bad inputs. See Sample Runs below.

Using Java, 1. Implement external sort: for sort phase use normal sort, for merge phase use two way merge to merge n sorted files (merge2way(n)), for array sort use heapsort. Also write merge(f1, f2, f3) to merge two sorted files f1 and f2 into f3.. Write mergenway(n) method and print execution time of both merges for initial input file over 10MB data. A sample input is as follow:Note:Fist input is max array size for sort 10 84 82 52 80 96 85 75 75 82 87 92 89 57 94 93 92 63 99 87 72 73 56 74 50 84 62 72 55 86 75 74 100 83 60 53 68 89 67 66 65 72 94 73 54 98 96 85 75 75 82 87 92 89

S1 and S2 are two sorted stacks of n and m numbers sorted in decreasing order, with their top items pointing to the smallest in their lists, respectively. Create a stack MERGE that merges the items in stacks S1 and S2, so that at the conclusion of the merge, all of the elements in S1 and S2 are available in MERGE in decreasing order, with the largest element at the top.Keep in mind that the number of components in stack MERGE is (n + m).
