The top-level domain (TLD) is the highest level in the domain name system (DNS) hierarchy. In the context of the Internet's DNS, the TLD is operationally positioned within the root zone of the namespace. Generally,.com is regarded as the premier choice, followed closely by.net and.org. For a website tailored for mobile optimization,.com would be the most suitable option.
public static int factorial(int n) {
if (n >= 1 && n <=12) {

Explanation: The factorial method takes a single integer n as input. It checks if n is within the range of 1 to 12. If it is, it further checks if n equals 1. If it is indeed 1, it returns 1 as the factorial. Otherwise, it recursively calls itself with n decreased by 1, multiplying the result by n. If n is outside this range, the method returns -1 indicating the input is invalid.
