Jump Search Multiple choice Questions and Answers (MCQs)

Question 1 [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Jump search algorithm requires which of the following condition to be true?
A
array should be sorted
B
array should have not be sorted
C
array should have a less than 64 elements
D
array should be partially sorted
Question 1 Explanation: 
Jump sort requires the input array to be sorted. The algorithm would fail to give the correct result if array is not sorted.

Question 2 [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Jumps are made in the jump search algorithm until .....
A
element having value less than that of the required element is found
B
element having value equal to the median of values of the array is found
C
element having value greater than that of the required element is found
D
middle element is found equal to the element being searched
Question 2 Explanation: 
In jump search algorithm jumps are made until element having value greater than the value of element being searched is found. After this linear search is performed in backwards direction.

Question 3 [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following step is taken after finding an element having value greater than the element being searched?
A
linear search takes place in the forward direction
B
linear search takes place in the backward direction
C
binary search takes place in the forward direction
D
binary search takes place in a backward direction
Question 3 Explanation: 
First an element having value greater than the element being searched is found. After this linear search is performed in a backward direction.

Question 4 [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How many jumps will be made in the worst case of jump search(let block jumped =k)?
A
n*k
B
n/k
C
k/n
D
n+k
Question 4 Explanation: 
Worst case occurs when the value to be searched is in the last section of the array. So, in this case the number of jumps will be n/k.

Question 5 [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What will be the maximum number of comparisons that can be made in jump search algorithm (assuming k to be blocks jumped)?
A
k
B
n/k
C
k-1
D
k-1
Question 5 Explanation: 
Worst case occurs when the element being searched is present just after the element that has been compared while making the last jump. So, in this case k-1 comparisons will have to be made.
