In computer science, the dining philosophers’ problem is an example problem often used in concurrent algorithm design to illustrate synchronization issues and techniques for resolving them. It was formulated in 1965 as a student exam exercise. It is still used now although many updates and solutions have been presented through the years. Write a code segment to solve the dining philosophers’ problem.

Exercise 2: In probability theory, one problem that often arises is determining the number of ways in which p objects can be selected from n distinct objects without regard to the order in which they are selected. Such selections are called combinations. The number of combinations of p objects from a set with n objects is C (n, p) and is given by: п! С(п, р) — (п- р)! * p! Write a Python program which will calculate and display on the screen the number of possible combination C based on the values of n and p; where both n and p are positive integers less than 21 and n >p. Implement and use at least the following three functions: fact(.): A function when passed a positive integer value, will calculate and return the factorial of that number. comb(..): A function when passed n and p (n: total number of objects and p: number of objects taken at a time) will calculate and return the total number of possible combinations (using the formula above). It calls function fact.) main(..): reads…

In python, no recursion

In C language please

Python

Python language only Suppose you are working in the pizza company named Dominoes. Dominoes provides the best in class pizza in the world so While dealing with the coustomer you got a number on every billed amount. SO here your task is to identifiy that the billing amount is a magic number or not. A number is said to be a magic number, if the sum of its digits are calculated till a single digit recursively by adding the sum of the digits after every addition. If the single digit comes out to be 1,then the number is a magic number.  Input : 1234Output : Yes it isInput : 12345Output : No it is not
