Question

Given the following sequence of names added to an ADT sorted list:nameListPtr->insertSorted("Tammie");nameListPtr->insertSorted("Brenda");nameListPtr->insertSorted("Sarah");nameListPtr->insertSorted("Tom");nameListPtr->insertSorted("Carlos");What would be returned by the call nameListPtr-> getPosition("Tammie")a. 1b. 3c. 4d. 5

Answer 1

c. 4

Step-by-step explanation:

This will work as following:

Lets say first Tammie is inserted by this statement insertSorted("Tammie")

Next insertSorted("Brenda") statement adds Brenda on top of Tammie so the sequence is now

1. Brenda
2. Tammie

Next insertSorted("Sarah"); statement inserts Sarah below Brenda and above Tammie so the sequence becomes:

1. Brenda
2. Sarah
3. Tammie

Next insertSorted("Tom"); statement inserts Tom below Tammie so the sequence becomes:

1. Brenda
2. Sarah
3. Tammie
4. Tom

Lastly insertSorted("Carlos"); statement inserts Carlos above sarah and below brenda so the sequence becomes:

1. Brenda
2. Carlos
3. Sarah
4. Tammie
5. Tom

Now the statement getPosition("Tammie") is called which returns the position value of Tammie. So as you can see above its position is 4th so output is 4.
