// Task 1. Children on the Flight.
// We are building Web application for the airlines.
// There is a page where we show list of passengers
// for the given flights.
// There is an age restriction:
// All children younger than 5 years old should have
// at least one adult parent or guardian.
// Parent/guardian should be at least 18 years old.
// We want to highlight all children who are not
// allowed to be on the flight.

// Task 2.  Maximum Budget Problem.

// We want to find out the most expensive trip combinations that can be purchased with a given budget. Given the price lists for two cities and a budget, find the total cost to buy them.
// Return maximum budget that can be spent, or -1 if it is not possible to buy both trips.
// Example 1
// Total trip budget = 10
// Paris trips = [3, 1]
// Barcelona trips = [5, 2, 8]

// Sample Output: 9

// Task 3. Price of simple parts

// We are selling computer hardware. We have products assembled from parts. 
// For example PC is build from motherboard, cpu, hard drive, etc. Some parts are simple: they have no sub parts like CPU. 
// When the part has subparts it is not simple. For example PC body has different subparts like covers, screws, etc.
// Every part has price. 

// Task:

// For a given list of parts find total price of the all simple parts.
