You must keep track of some data. Your options are: (1) A linked-list maintained in sorted order. (2) A linked-list of unsorted
ladessa [460]

Answer:

Question was incomplete and continued the question

For each of the following scenarios, which of these choices would be best? Explain your answer.

BST

Sorted Array

Un-sorted Array

a) The records are guaranteed to arrive already sorted from lowest to highest (i.e., whenever a record is inserted, its key value will always be greater than that of the last record inserted). A total of 1000 inserts will be interspersed with 1000 searches.

b) The records arrive with values having a uniform random distribution (so the BST is likely to be well balanced). 1,000,000 insertions are performed, followed by 10 searches.

Explanation:

Answer for a: Un-sorted array or Un-sorted linked list : as mentioned in the question itself that the records are arriving in the sorted order and search will not be O(log n) and insert will be not be O(n).

Answer for b : Un-sorted array or Un-sorted linkedlist : Number of the items to be inserted is already known which is 1,000,000 but it is very high and at the same time search is low. Unsorted array or Unsorted linked list will be best option here.

Explain why regular system cleanup is vital to ensuring the operating system runs efficiently.
Oksanka [162]
Cleaning up a system helps clear up the space on the drives. It may also clear up processor usage, ram usage if you uninstall programs that automatically started when the system booted. You may also delete some unwanted programs in the process.

Overloading in methods are popular in programming, and why overloading is important.
Cerrena [4.2K]

Answer:

 Yes, overloading is one of the methods which are popular in programming language. Overloading basically refers to the same function but different signature called function overloading or method overloading. It is the ability to define the multiples method by using the single identifier.

The overloading is important because it has the ability to design the multiple method by using similar name. It also provide the high flexibility to the programmers to call the same method in the data. overloading basically provide the high clarity in the code.

Overloading is used to achieved the compile time polymorphism.  

Following are program of function overloading in c++ are:

Class abc // creating class

{

public:

int p;

void fun() // function fun with no parameter/

{

cout<<” hello “;

}

void fun(int a) // function fun with parameter

{

p=a;

cout<<p;

}

};

int main() // main function

{

abc ob; // creating object

ob.fun();// print hello;

ob.fun(6);// print 6

return 0;

}

Explanation:

In this program the function fun() have same name but different signature in the main method we create the object of class abc i.e ob. ob.fun() this statement called the function with no parameter and ob.fun(6) this statement will called the function with integer parameter.

Suppose you have a file of data of approximately 100,000 personnel records (FYI, 213 = 8192 and 214 = 16384) using Social Securi
Natali [406]

Answer:

See explaination

Explanation:

The reasons why indexed sequential search structure is better are:

1. In index sequential search any field of the records can be used as the key. This key field can be numerical or alphanumerical.

2. Since each record has its data block address, searching for a record in larger database is easy and quick. There is no extra effort to search records. But proper primary key has to be selected to make efficient.

3. This method gives flexibility of using any column as key field and index will be generated based on that. In addition to the primary key and its index, we can have index generated for other fields too. Hence searching becomes more efficient, if there is search based on columns other than primary key.

The reasons why 5 B-tree is better:

1.The B-tree Provides support for range of queries in an efficient manner and You can iterate over an ordered list of elements.

2. B-Tree algorithms are good for accessing pages (or blocks) of stored information which are then copied into main memory for processing. In the worst case, they are designed to do dynamic set operations in O(lg n) time because of their high "branching factor" (think hundreds or thousands of keys off of any node). It is this branching factor that makes B-Trees so efficient for block storage/retrieval, since a large branching factor greatly reduces the height of the tree and thus the number of disk accesses needed to find any key.

3. It is a generalization of a BST in that a node can have more than two children. These are self-balancing and hence the average and worst complexities is logarithmic. We opt for these when the data is too huge to fit in main memory. These structures are used in database indexing and help in faster operations on disk

the additional informations is we should first decide to choose which structure is suiatable for which algoritm in terms of space and time and then use the appropriate search algorithm.
