Suppose that someone starts with a chain letter. Each person who receives the letter is asked to send it on to 4 other people. Some people do this, while some do not send any letter. How many people have seen the letter, including the first person, if no one receives more than one letter and if the chain letter ends after there have been 100 people who read it but did not sendit out ? Also find how many people sent out the letter ?
| A. | 122 & 22 |
| B. | 111 & 11 |
| C. | 133 & 33 |
| D. | 144 & 44 |
|
Option: C Explanation :
4-ary tree
People who saw the letter = nodes
People who did not send the letter= leaves (100)
People who sent the letter: internal nodes (
n= (4.100-1)/ (4-1) =133 nodes
i= (100-1)/ (4-1) = 33
A full m-ary tree with
I.n vertices has i=(n-1)/m internal vertices and l= [(m-1) n+1]/m leaves
II. i internal vertices has n=mi + 1 vertices and l= (m+1)i+1 leaves
III.l leaves has n =(ml-1)/(m-1) vertices and i= (l-1)/ (m-1) internal vertices

from the option :a) n=22 who read but not forward including one is root(source) if n=22 persons send to next 4 person then total is 88 1=89 !=122 ------ignoresame for b) in case c) n=33 just read ,not forwardif forward then 33*4 1(source)=133 -----answerd) n=44 forwarded = 44*4 1=177 ------ignore

it is based on 4-ary tree People who saw the letter = nodesPeople who did not send the letter= leaves (100)People who sent the letter: internal nodesn= (4.100-1)/ (4-1) =133 nodesi= (100-1)/ (4-1) = 33

A hash function f defined as f (key) = key mod 13, with linear probing is used to insert keys 55, 58, 68, 91, 27, 145. What will be the location of 79 ?
| A. | 1 |
| B. | 2 |
| C. | 3 |
| D. | 4 (correct answer is 5) |

79 should be in location no 5 bcz 4 is already fill with 68 bcz 55 is place in loc no 3 and next 68 will be 4th posion
