You are given a positive integer N and an equation 1/X + 1/Y = 1/N

You need to determine the count of all possible positive integral solutions (X, Y) for the above equation.

Note:

1. X and Y should be greater than 0.
2. (X, Y) and (Y, X) are considered different solutions if X is not equal to Y, i.e. (X, Y) and (Y, X) will not be distinct if X=Y.

You have been given an array/list “BOOKINGS” of booking details of ‘N’ flights from 1 to ‘N’. Each booking detail contains three positive integers [first, last, seats] which represent a booking for flights “first” through “last” (inclusive) with “seats” seats reserved for each flight in the range.

Now, you are supposed to return an array/list “ANSWER” of length ‘N’, where answer[i] represents the total number of seats reserved for ith flight.

Given that integers are read from a data stream. Your task is to find the median of the elements read so far.

Median is the middle value in an ordered integer list. If the size of the list is even there is no middle value. So the median is the floor of the average of the two middle values.

For example :

[2,3,4] - median is 3.
[2,3] - median is floor((2+3)/2) = 2.

You are given a list of ‘N’ words ‘WORDS’. Your task is to return all pairs of the distinct indices (i, j) in ‘WORDS’, such that the concatenation of WORDS[i] and WORDS[j] is a palindrome.

For Example:

You are given ‘WORDS’ = [“cat”, “mat”, “tac”]. Then the answer will be [(0, 2), (2, 0)}, because “cat” + “tac” = “cattac” which is a palindrome and “tac” + “cat” = “taccat” which is also a palindrome.
