Given a directed graph, check whether the graph contains a cycle or not. Your function should return true if the given graph contains at least one cycle, else return false.

You have been given two arrays, 'AT' and 'DT', representing the arrival and departure times of all trains that reach a railway station.

Your task is to find the minimum number of platforms required for the railway station so that no train needs to wait.

Note :

1. Every train will depart on the same day and the departure time will always be greater than the arrival time. For example, A train with arrival time 2240 and departure time 1930 is not possible.

2. Time will be given in 24H format and colons will be omitted for convenience. For example, 9:05AM will be given as "905", or 9:10PM will be given as "2110".

3. Also, there will be no leading zeroes in the given times. For example, 12:10AM will be given as “10” and not as “0010”.

Mr. X is a professional robber planning to rob houses along a street. Each house has a certain amount of money hidden.

All houses along this street are arranged in a circle. That means the first house is the neighbour of the last one. Meanwhile, adjacent houses have a security system connected, and it will automatically contact the police if two adjacent houses are broken into on the same night.

You are given an array/list of non-negative integers 'ARR' representing the amount of money of each house. Your task is to return the maximum amount of money Mr. X can rob tonight without alerting the police.

Note:

It is possible for Mr. X to rob the same amount of money by looting two different sets of houses. Just print the maximum possible robbed amount, irrespective of sets of houses robbed.

For example:

(i) Given the input array arr[] = {2, 3, 2} the output will be 3 because Mr X cannot rob house 1 (money = 2) and then rob house 3 (money = 2), because they are adjacent houses. So, he’ll rob only house 2 (money = 3)

(ii) Given the input array arr[] = {1, 2, 3, 1} the output will be 4 because Mr X rob house 1 (money = 1) and then rob house 3 (money = 3).

(iii) Given the input array arr[] = {0} the output will be 0 because Mr. X has got nothing to rob.

• Explain Virtual Memory Management

• What is different between main memory and secondary memory?

You are the Librarian of the Ninja library. There are ‘N’ books available in the library and ‘B’ ninjas want to read the books. You know the number of pages in each book and you have to allocate the books to the ‘B’ ninjas in such a way that the maximum number of pages allocated to a ninja is minimum.

Note

A book will be allocated to exactly one ninja. 
At least one book has to be allocated to a ninja.
Allotment of the books should be done in a contiguous manner. For example, a ninja can not be allocated book 2 and book 4, skipping book 3.

The task is to return the minimum of the maximum number of pages allocated to a ninja.

Find ages of daughters

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?
