Mr. Naughty loves to play with balls. So, his friend, Mr. Nice, gave him n balls to play the game. Each ball has exactly two numbers (more number and number below). In one move Mr. Naughty can rotate any ball that its bottom is now rising. Mr. Nice knows a small amount of this movements that can make at least half of the balls show the same number at the top. So, in order to win Mr Nice's game, Mr. Naughty has to earn a small amount of it it goes. It is not always possible to make such movements that satisfy what is provided in this case Mr. Naughty should see that it is "Impossible" to make such movements. Help Mr. Naughty win the game.

Topological Sort

Topological sort is a sorting technique that sets up a hierarchy in a process. In this technique, when a directed network has nodes connected by arrows, the root node is placed before the successor node.

You have a mixed pile of N nuts and N bolts and need to quickly find the corresponding pairs of nuts and bolts. Each nut matches exactly one bolt, and each bolt matches exactly one nut. You can see which is larger by fitting a nut and bolt together, but it is not possible to directly compare two nuts or two bolts.
A chess knight, on one turn, moves either two squares vertically and one horizontally, or two horizontally and one vertically. If we consider a knight starting at the point ⟨x, y⟩ in Z × Z, it has eight possible moves, to ⟨x+1,y+2⟩,⟨x+1,y−2⟩,⟨x−1,y+2⟩,⟨x−1,y−2⟩,⟨x+ 2, y + 1⟩, ⟨x + 2, y − 1⟩, ⟨x − 2, y + 1⟩, or⟨x − 2, y − 1⟩. (a) Prove that given any two points ⟨x, y⟩ and ⟨x′, y′⟩ in Z × Z, there is a sequence of knight moves from the first point to the second. (b) Let a and b be different positive naturals. An (a, b)-knight also has eight possible moves, from ⟨x,y⟩ to ⟨x±a,y±b⟩ or ⟨x±b,y±a⟩. What conditions on a and b allow the (a, b)-knight to go from any point in Z × Z to any other? Prove your answer. (c) If a and b do not meet the conditions of part (b), exactly which points can the (a,b)- knight reach from ⟨x, y⟩

Dreamworld is known for his uniqueness and there are 2 different denomination coins in Dreamworld, 1-cent coins and 2 cents coins. They have two faces - heads and tails. Your job is to find a number of ways to make a line order for these coins using the Python Code so that their total value is N cents. The only condition in line planning is that the first coin in the plan should have heads at the top. All other coins can have tails or heads at the top. Take N = 2 as an example. Possible arrangements are (1H, 1H), (2H), (1H, 1T), where H is primary and T is the tail. So, there are 3 possible plans that cost 2 cents. Input: 1 3 Output: 8

Holi is celebrated in India as a festival of colours and your friend Khan from India has gifted you X packets of colours. Now you are planning to make a beautiful rangoli, to make it you need to map all colours pairwise distinct, so that they look attractive. To do so, you can mix the colours zero or more times: o Pick any two random colours. Let's denote their weight by t and u. o Mix the colour with second colour. After the process, the value of the first colour remains t, but the weight of the second colour changes to t + u. Now you have to develop a python code to find the minimum number of mixing operations you needs to perform to make a beautiful Rangoli. Sample Test Case Scenario: 1 4 5324 Output:
