Answer:
root is an ancestor of all other nodes in a tree.
Explanation:
Root is a special node in the tree which is an ancestor of all other nodes.For example, consider a binary tree with root R. Let C1,C2 be the children of R at level 1. Similarly, C11,C12 are the children of C1 at level 2 and C21,C22 are the children of C2 at level 2. Now the parent of C22 is C2 and the parent of C2 is root R. Similar is the case for all other child nodes. Hence, Each node in the tree will have the root node R as its ancestor.

John is the JAD project leader
Joint Application Development (JAD) is a process that accelerates the design of information technology solutions. JAD uses customer involvement and group dynamics to accurately depict the user's view of the business need and to jointly develop a solution.
The executive sponsor is the person from the customer's organization who has the ultimate authority to make decisions about the project. The sponsor may be the customer's project leader, the CIO, or, in some cases, the CEO. The facilitator works with the sponsor to get the project started; it is essential, however, that the sponsor make key decisions, not the facilitator.

. Accept ultimate authority and responsibility for the functional area to be addressed by the system.
· Resolve business policy conflicts by being the ultimate decision? maker.
· Honor the results of the JAD process.
· Set the vision for the project.
· Ensure the project team has access to and commitment from the right business user experts.
· Communicate customer support and cooperation.
Answer:
Explanation:
The following function/program is written in Java. It asks the user for a sentence as an input and then splits that sentence into an array of words. Then it creates an arrayList for all of the unique words, comparing each word in the sentence with all of those in the ArrayList. If a word is found in the ArrayList it cancels the loop and moves on the next word in the sentence. Finally, it counts all of the unique words in the ArrayList and prints that total to the screen.
public static void uniqueWords() {
Scanner in = new Scanner(System.in);
System.out.println("Enter a sentence:");
String sentence = in.nextLine();
String words[] = sentence.split(" ");
ArrayList<String> uniqueWords = new ArrayList<>();
for (int x = 0; x < words.length; x++) {
boolean exists = false;
for (int i = 0; i < uniqueWords.size(); i++) {
if (words[x].equals(uniqueWords.get(i))) {
exists = true;
break;
}
}
if (exists == false) {
uniqueWords.add(words[x]);
}
}
System.out.println(uniqueWords.size());
}
<u>Answer:</u>
<em>When system feasibility is being determined </em>
<u>Explanation:</u>
<em>Prototyping is the part of Requirement and Analysis phase. </em>It is the phase where the client and the development team sits and discuss about what the requirement is and show <em>a model of what are all the things which they could bring up the requirement as a software. </em>
So here, the prototyping is really essential to visually understand how the team has interpreted the requirement and how far it matches with the client. <em>All the other options stands invalid in the given context.</em>
