For results that cannot be stored in a long variable, we use BigInteger variable declared in java.math library. Example 2: Find Factorial of a number using BigInteger import java.math.BigInteger; public class Factorial { public static void main(String[] args) { int num = 30; BigInteger fac...

1.write a program which computes and prints prime numbers 2. write a program which computes and prints the factorial of a number
It looks like no matter what the value of (0-1)! turns out to be, the result should always be 0! = 0, but things are more complicated than that in maths. In the previous section, we saw that the n-factorial is only defined for n > 0, so we have a problem here. The term ...

1.BigIntegerclass is in java.math package, so you need to specifically import it, it will not be imported automatically like java.lang package. 2. Similar to String,BigIntegerclass is also immutable, so any modification e.g. addition, multiplication will produce a new instance ofBigInteger, le...
specifies that factorial is a predicate of arity 2, with known first and unknown second argument. Keyword procedure describes the behavior of predicate, indicating that is will always succeed with only one solution, so no backtracking is required. In main.pro the actual description of newly specif...

Programmers have spent several months studying this problem but with no results. They were unable to find the solution fast enough. After a long time, one of the programmers found this problem in a conference article. Unfortunately, he found that the problem is so called "Travelling Salesman ...
