System Engineer Specialist

A, B and C can do a piece of work in 20, 30 and 60 days respectively. In how many days can A do the work if he is assisted by B and C on every third day?

You are given the price of ‘Petrol’ cars, the maintenance cost of the car per month, number of kilometers a car runs in one liter, amount of Petrol per liter, and number of kilometers a car can run per month. Similar details are also given for ‘Diesel’ cars.

Your task is to find which car ( ‘Petrol’ or ‘Diesel’ ) is efficient to use for an exact 6 month period. If your answer is ‘Petrol’ car then print ‘0’, if your answer is ‘Diesel’ car then print ‘1’, if both the cars ( ‘Petrol’ and ‘Diesel’) are efficient then print ‘-1’.

For example, consider both the cars:

Price of ‘Petrol’ car = ‘780000’, the maintenance cost of ‘Petrol’ car per month = ‘500’, number of kilometers a ‘Petrol’ car can run in one liter  = ’35’, price of ‘Petrol’ per liter = ‘75’ and number of kilometers a ‘Petrol’ car can run in a month = ‘145’.

Similar details are given for ‘Diesel’ car, price of ‘Diesel’ car = ‘850000’, the maintenance cost of ‘Diesel’ car per month = ‘1000’, number of kilometers a ‘Diesel’ car can run in a one-liter = ’30’, price of ‘Diesel’ per liter = ‘80’ and number of kilometers a ‘Diesel’ car can run in a month = ‘200’.

Then the ‘Petrol’ car will be more efficient, so we will print the integer ‘0’.

Given a matrix ‘UNIVERSE’ with 3 rows and ‘N’ columns, with the characters { # , * , . } and these characters represent a cluster of stars and galaxies in space. Stars are represented by ‘*’ symbol. The ‘.’ symbol represents empty space.

We define a constellation as a 3x3 matrix which contains stars in the shape of vowels. A group of constellations is defined as a galaxy. Note that a galaxy may contain many stars but they will never be overlapping. Two galaxies are separated by a column of ‘#’.

Given the ‘UNIVERSE’ matrix, print a string which denotes all the vowels formed by stars and ‘#’ present in the matrix.

A looks like this :

Note :

It is guaranteed that no two constellations are overlapping.

You are given a non-empty string S containing no spaces’ and a dictionary of non-empty strings (say the list of words). You are supposed to construct and return all possible sentences after adding spaces in the originally given string ‘S’, such that each word in a sentence exists in the given dictionary.

Note :

The same word in the dictionary can be used multiple times to make sentences.
Assume that the dictionary does not contain duplicate words.
