Task 03: Read the concept of Binomial coefficient given in chapter-6. Write a method that
takes two parameters n and k and returns the value of Binomial Coefficient C(n, k).
For example, your function should return 20 for n = 6 and k = 3, and it should return 35 for n= 7 and k
= 4. ( confirm it through the Pascal's triangle as given below).

We will rewrite the Sales Bar Chart question to use method for printing out the bar chart. The part where the asterisks are printed out should be done with a method. Use this method for each bar.
The original question statement is here:
Write a program that asks the user to enter today’s sales for five stores. The program should
display a bar chart comparing each store’s sales. Create each bar in the bar chart by displaying
a row of asterisks. Each asterisk should represent $100 of sales. Here is an example of
the program’s output:
Enter today's sales for store 1: 1000 [Enter]
Enter today's sales for store 2: 1200 [Enter]
Enter today's sales for store 3: 1800 [Enter]
Enter today's sales for store 4: 800 [Enter]
Enter today's sales for store 5: 1900 [Enter]

- Please help me create a cave class for a Hunt the Wumpus game. You can read the rules in it's entirety of the Hunt the Wumpus game online to get a better idea of the specifications. It's an actual game. INFORMATION: The object of this game is to find and kill the Wumpus within a minimum number of moves, before you get exhausted or run out of arrows. There is only one way to win: you must discover which room the Wumpus is hiding in and kill it by shooting an arrow into that room from an adjacent room. The Cave The Wumpus lives in a cave of 30 rooms. The rooms are hexagonal. Each room has up to 3 tunnels, allowing access to 1, 2 or 3 (out of 6) adjacent rooms. The attached diagram shows the layout of rooms in the cave. The map wraps around such that rooms on the edges (white cells) have neighbors from the opposite edge (blue cells). E.g., the neighbors of room 1 are rooms 25, 26, 2, 7, 6, and 30, and you could choose to connect room 1 to any of these rooms.

Theobjective of the game is to determine the position of these stars. To help withidentifying the correct position, some slots contain hints in the form of numbers.These hints work like the number hints in minesweeper in the sense that itidentifies how many stars are adjacent to the slot. The range of values are from0 (no stars) to 8 (fully surrounded by stars). A Tentaizu puzzle contains only thesenumber hints. Much like other puzzle games like sudoku, there is only onecombination of star positions that is described by the puzzle.2. Your task is to create a solver function for a given Tentaizu puzzle. This functionshould be able to recursively solve the puzzle. Define a function “solve” with theinput variable being a 7x7 list representing the Tentaizu puzzle.
