Program To Check Prime Number In Prolog
Prolog program to check prime number, Search on prolog program to check prime number.
Solutions can be found. 2.01 (.) Determine whether a given integer number is prime. Example:?- isprime(7). Yes 2.02 (.) Determine the prime factors of a given positive integer. Construct a flat list containing the prime factors in ascending order. Example:?- primefactors(315, L). L = 3,3,5,7 2.03 (.) Determine the prime factors of a given positive integer (2).
Construct a list containing the prime factors and their multiplicity. Example:?- primefactorsmult(315, L). L = 3,2,5,1,7,1 Hint: The solution of problem 1.10 may be helpful. 2.04 (.) A list of prime numbers. Given a range of integers by its lower and upper limit, construct a list of all prime numbers in that range.
2.05 (.) Goldbach's conjecture. Goldbach's conjecture says that every positive even number greater than 2 is the sum of two prime numbers. Example: 28 = 5 + 23. It is one of the most famous facts in number theory that has not been proved to be correct in the general case.
C Program To Check Prime Or Not
It has been numerically confirmed up to very large numbers (much larger than we can go with our Prolog system). Write a predicate to find the two prime numbers that sum up to a given even integer. Example:?- goldbach(28, L). L = 5,23 2.06 (.) A list of Goldbach compositions.
Given a range of integers by its lower and upper limit, print a list of all even numbers and their Goldbach composition. Example:?- goldbachlist(9,20). 10 = 3 + 7 12 = 5 + 7 14 = 3 + 11 16 = 3 + 13 18 = 5 + 13 20 = 3 + 17 In most cases, if an even number is written as the sum of two prime numbers, one of them is very small. Very rarely, the primes are both bigger than say 50. Try to find out how many such cases there are in the range 2.3000. Example (for a print limit of 50):?- goldbachlist(1,2000,50). 992 = 73 + 919 1382 = 61 + 1321 1856 = 67 + 1789 1928 = 61 + 1867 2.07 (.) Determine the greatest common divisor of two positive integer numbers.
Use Euclid's algorithm. Example:?- gcd(36, 63, G). G = 9 Define gcd as an arithmetic function; so you can use it like this:?- G is gcd(36,63). G = 9 2.08 (.) Determine whether two positive integer numbers are coprime. Two numbers are coprime if their greatest common divisor equals 1. Example:?- coprime(35, 64).
Yes 2.09 (.) Calculate Euler's totient function phi(m). Euler's so-called totient function phi(m) is defined as the number of positive integers r (1. Free program manual como pintar un automovil.
A very straight-forward solution uses CLP(FD) constraints to express the desired properties. We start with a simpler predicate, which is true iff the number is composite: iscomposite(N):- N #= A.B, A,B ins 2.sup. The exact usage details for CLP(FD) constraints differ slightly between Prolog systems. With at most small modifications, you will be able to run the above in all most widely used systems.
Because: A prime number is an integer greater than 1 that is not composite. Here are a few examples:?- length(, , P), + iscomposite(P).
P = 2; P = 3; P = 5; P = 7; P = 11; P = 13; P = 17; P = 19; P = 23; P = 29; etc. In general, it is good practice to use CLP(FD) constraints when reasoning over integers in Prolog.
