Answer:
3) A Single linked list is a sequence of elements in which every element has link to its next element in the sequence.
DATA LINK
DATA stores actual value , LINK stores address of next node
As per information given in question, letters at the even addresses are items in linked list and the odd addresses will be used as links.
Even Address Odd Address
12 (Stores 't') 13 (Used as link)
14 (Stores 'm') 15 (Used as link)
16 (Stores 'a') 17 (Used as link)
18 (Stores 'r') 19 (Used as link)
20 (Stores 's') 21 (Used as link)
Numbers represented by circle are addresses of respective nodes. Here Front or Head has address 16. Which represents the Head Node.
Following image represents the word "smart" with respective nodes and their addressing.
Numbers represented by circle are addresses of respective nodes.
The head pointer is: 20
Answer:
C. Mean
Explanation:
Mean = (∑
)/N
Median = central values when data is sorted
Mode = most repeated value
Standard deviation = 
In standard deviation, formula you may see that deviation is being calculated from the mean (central location). But here we take square of the value before adding all of them.
But if we just take 
, it would be equal to zero.
<u>EXAMPLE</u>
Take 4, 9, 5 as data
mean = (4+9+5)/3 = 18/3 = 6
sum of deviations from mean = (4-6)+(9-6)+(5-6) = (-2)+(3)+(-1) = 0
