In which of the following cases dynamic arrays are not preferred?
a) If the size of the array is unknown
b) If the size of the array changes after few iterations
c) If the memory reallocation takes more time i.e. expensive
d) If the array holds less number of elements

In special case, the time complexity of inserting/deleting elements at the end of dynamic array is __________
a) O (n)

c) O (log n)
d) O (1)

You are given a Singly Linked List of integers. Return true if it has a cycle, else return false.

A cycle occurs when a node's next points back to a previous node in the list.

Example:

In the given linked list, there is a cycle, hence we return true.

You are given an integer array of size N. Your task is to rotate the array by one position in the clockwise direction.

For example :

If N = 5 and arr[ ] = {1, 2, 3, 4, 5} then output will be 5 1 2 3 4.

If N = 8 and arr[ ] = {9, 8, 7, 6, 4, 2, 1, 3} then output will be 3 9 8 7 6 4 2 1.

Alok has three daughters. His friend Shyam wants to know the ages of his daughters. Alok gives him first hint. 
1) The product of their ages is 72. 
Shyam says this is not enough information Alok gives him a second hint. 
2) The sum of their ages is equal to my house number. 
Shyam goes out and looks at the house number and tells “I still do not have enough information to determine the ages”. 
Alok admits that Shyam can not guess and gives him the third hint 
3) The oldest girl likes strawberry ice cream. 
Shyam is able to guess after the third hint. Can you guess what are the ages of the three daughters?

There are 3 devils and 3 Priests.They all have to cross a river in a boat.Boat can only carry two people at a time.As long as there are equal number of devils and priests,then devils will not eat Priest.If the number of devils are greater than the number of priests on the same side of the river then devils will eat the priests.So how can we make all the 6 peoples to arrive to the other side safely?

You are given an integer ‘NUM’ . Your task is to find out whether this number is an Armstrong number or not.

A k-digit number ‘NUM’ is an Armstrong number if and only if the k-th power of each digit sums to ‘NUM’.

Example

153 = 1^3 + 5^3 + 3^3.

Therefore 153 is an Armstrong number.

Which of the following is not an example of DBMS?
a) MySQL
b) Microsoft Acess
c) IBM DB2
d) Google

You are given an integer ‘N’. You have to print the value of Factorial of ‘N’. The Factorial of a number ‘N’ is defined as the product of all numbers from 1 to ‘N’.

For Example:

Consider if ‘N’ = 4, the Factorial of 4 will be the product of all numbers from 1 to 4, which is 1 * 2 * 3 * 4 = 24. Hence, the answer is 24.
