Data Structure Questions and Answers

Why are the elements of an array stored successively in memory cells?

The elements of an array are stored successively so that the computer can keep track the first element’s address. It is helpful to the user or administrator as they can easily search for the latest element they run or used. The previous elements or addresses are calculated. These have been tracked before new elements are added. The computer will only calculate the disk space they occupy, etc. This can be easily remembered by comparing it to you, getting and wearing the shirt on the top pile of your cabinet knowing that you have 10 shirts below it. Once you add a new address on your computer in your next use, it will be then the one that is being tracked.

What is a good practice for a developer to follow when writing a trigger?

If a data structure developer is writing a trigger then it is a good practice for them to use the Map data structure to hold query results by ID and use the Set data structure to ensure distinct records. A trigger is an SQL (structured Query Language) procedure that initiates an action when an event occurs. A trigger is something that cannot be called or executed but instead automatically fires as a result of a data modification. SQL is the primary language that is used to communicate with a database. It is officially the standard language for relational database management systems.

What is the order of the algorithm? Running time of an algorithm T(n), where n is input size is given by T(n) = 8 T(n/2) + qn, if n>1 T(n) = p, if, n=1 where p and q are constants.

The order of the algorithm is letter C. An algorithm is known to be a set that is composed of rules and other operations that will be followed by devices. The computer uses this often in order to serve certain problems easily. Even if this is done by computers and other gadgets in a short amount of time, this follows a step-by-step process. If this process is not followed, then the wrong answer may be received. This will not be ideal at all. Aside from being used for complicated calculations, algorithms can also be used to do data processing and reasoning tasks.

Which of the following statements about linked list data structure is/are TRUE?

Each element of a list is comprised of two items, which is the data and a reference to the next node. The final node provides the reference to null. The entrance point into a linked list is called the head of the list. A linked list is a dynamic data structure, and linked lists are beneficial in dynamic memory allocation. Those lists are used in operating systems. Insertion and deletion in related records are used in operating systems. Addition and deletion and complex data structures like tree graphs are implemented using linked lists.
