Answer:

A linked list is a data structure that has sequence of nodes where every node is connected to the next node by means of a reference pointer. The elements are not stored in adjacent memory locations. They are linked using pointers to form a chain. This forms a chain-like link for data storage.

Subject: ACT

Question:

Example of an ACT question I can help you answer: Ms. Hernandez began her math class by saying: I’m thinking of 5 numbers such that their mean is equal to their median. If 4 of the numbers are 14, 8, 16, and 14, what is the 5th number? What is the 5th number Ms. Hernandez is thinking of?

Answer:

The correct answer is 18. Since there will be an odd number of terms, the median will have to be the middle number. Write out the numbers in the original set in numerical order. You will see no matter where you place the 5th term, the median will be 14. Ms. Hernandez said that the mean is equal to the median, so the mean is also going to be 14. If x = the 5th number, then the mean is 14 = . So, 14(5) = 52 + x, or x = 18.
