Using the C++ programming language. At the station the child marks the colour of any bogie of any colour from V-Violet, Indigo, B-Blue, G-Green, Y-Yellow, O-Orange, R-Red. A few trains come and go and are provided with the S series. The stationmaster's favourite train consists of bogies with a combination of colours identified by the series F. It is noted that at the station, every hour, passes X bogies.

Alice, a friend of Mr. Bernard’s, wants to compose a song. She asks Mr. Bernard for help. Although Mr. Barnard knows nothing about music, he finds that the sequence of notes in a numbered musical notation can be expressed as an FSM with input the alphabet {1, 2, 3, 4, 5, 6, 7} (“do”, “re”, “mi”, “fa”, “so”, “la”, “ti”). a) Alice wants to compose a song that contains the pattern “15” an even number of times. Please draw an FSM that only accepts a sequence of notes that satisfies the above pattern. b)Alice changes her mind. She finds that it would be enough to just use {1, 5} (“do”, “so”) in her new song. She wants to compose a song satisfying the following two conditions: i)If the sequence of notes ends with “1”, it should contain an even number of digits. ii)If the sequence of notes ends with “5”, it should contain an odd number of digits. Please draw an FSM that only accepts the sequences of notes that satisfy the above conditions.Note that you should provide a detailed description of…

Note: Please Answer in C++ only Chef and his little brother are playing with sticks. They have total N sticks. Length of ith stick is Ai. Chef asks his brother to choose any four sticks and to make a rectangle with those sticks its sides. Chef warns his brother to not to break any of the sticks, he has to use sticks as a whole. Also, he wants that the rectangle formed should have the maximum possible area among all the rectangles that Chef's brother can make. Chef's little brother takes this challenge up and overcomes it. Can you also do so? That is, you have to tell whether it is even possible to create a rectangle? If yes, then you have to tell the maximum possible area of rectangle. Input Output 1 5 12312
Answer this in C++ Asap Alice and Bob play a game. At first, there is only one tree with roots. The players take turns, Alice begins. At one point, Alice has to pick up any empty underground tree roots (or shrubs) and remove them. Bob, on the other hand, has to pick out any part of the empty leaves and remove them from the tree (or trees). (Please note that Bob always takes some depth from the leaves of the first tree.) It is not allowed to skip the turn. The game ends when the player is unable to take a chance. Alice's goal is to reduce the number of turns made by both players, while Bob wants the number to be greater. Considering that they both played very well, how many turns did they make last?

WRITE CODE IN C LANGUANGE On their way down the river, Jojo and Lili saw two frogs each in position X1 and X2. The two frogs are seen jumping happily towards the same direction that is come to Jojo. After watching the two frogs, Joio and Lili saw that the speed the two frogs are different. The first frog to start jumping from position X1 has a speed of v1, while the second frog that starts to jump from position X2 has a speed of V2. Joig guess that "YES" both frogs will be in the same position in a certain time T, while Bibi guessing "NO" the two frogs will never be in the same position in time. Help Joio and Lili calculate the frog's movements to determine whether the guess they are right
Use Sage to program Exercise 5.In 1202 AD, Leonardo Pisano asked the following famous problem:A certain man had a pair of rabbits together in a certain enclosedplace, and one wishes to know how many are created from the pair inone year when it is the nature for of them in a single month to bearanother pair, and in the second month those born bear also. Becausethe abovewritten pair in the first month bore, you will double it. therewill be two pairs in one month. One of these, namely the first, bears inthe second month, and thus there are in the second month three pairs;of these in one month two are pregnant, and in the third month 2pairs of rabbits are born, and thus there are 5 pairs in the month;...Explain how the rabbits reproduce. Create a list F where F[x] is the number ofrabbits in month x. (so F[0]=1, F[1]=2) Find F[12]. Find F[100].
Write a code in C++ / cpp to solve the following problem In a hypothetical island, one can buy land in squares where the length of a square side must be a positive integer amount of meters. Buying a square of land with a side a costs a2 rhombics (a local currency). Sasha has decided to invest all of her N rhombics into the land. She can, surely, do it, buying square pieces 1 × 1 meters. At the same time she has requested to minimize the amount of pieces she buys. Can you find out the number of pieces she has bought ? Input The only line contains a positive integer N ≤ 60 000 , that is a number of rhombics that Sasha has invested. Output The only line contains the number of pieces she has bought.
