A more efficient version of the function for computing Tetranacci numbers can be defined by following three steps:

1. Implement a function which takes a list of integers and adds the sum of the top four elements to the head of the list (e. g., in F#, 1::1::1:1::/) should become 4:-1:-1::1::1::]).
2. Implement a recursive function which accepts an integer n as input (again, assumen > 0), and returns a list of integers from 0 to n in ascending order
3. Implement a recursive function which computes the nth Tetranacci number in linear time. This function may use a linear amount of space to compute its result, but the number of recursive calls it makes must be linear in n. Your task is to follow the three steps above, in order to implement the requested function in F

Write a modular program (no classes yet, just from what you learned last year), that allows two players to play a game of tic-tac-toe. use a two-dimensional char array with 3 rows and 3 columns as the game board. each element of the array should be initialized with an asterisk (*). the program should display the initial board configuration and then start a loop that does the following: allow player 1 to select a location on the board for an x by entering a row and column number. then redisplay the board with an x replacing the * in the chosen location. if there is no winner yet and the board is not yet full, allow player 2 to select a location on the board for an o by entering a row and column number. then redisplay the board with an o replacing the * in the chosen location. the loop should continue until a player has won or a tie has occurred, then display a message indicating who won, or reporting that a tie occurred. player 1 wins when there are three xs in a row, a column, or a diagonal on the game board. player 2 wins when there are three ox in a row, a column, or a diagonal on the game board. a tie occurs when all of the locations on the board are full, but there is no winner. input validation: only allow legal moves to be entered. the row must be 1, 2, or 3. the column must be 1, 2 3. the (row, column) position entered must currently be empty (i.e., still have an asterisk in it).
