Answer:
The method is as follows:
public static int lastIndexOf(int [] numbers, int num){
int lastIndex = numbers[0];
for(int i =0; i<numbers.length;i+=num){
lastIndex = numbers[i];
}
return lastIndex;
}
Explanation:
This defines the method
public static int lastIndexOf(int [] numbers, int num){
This initializes the lastIndex to the first element of the array
int lastIndex = numbers[0];
This iterates through every "num" element of the array
for(int i =0; i<numbers.length;i+=num){
This gets the current index... until the last
lastIndex = numbers[i]; }
This returns the last
return lastIndex; }

Listed below are the few ways Linux Server can be secured
1. Group policies: This is a way to ensure security by applying group policies and permissions both on the group level and the files level. Through proper permission configuration we can easily restrict other users from accessing those files and directories.
2. Implementation of the firewall: Implementing firewall in each of the Linux server will definitely help in securing your machine from outside threats. Iptables will help in filtering the network traffic that are entering into the system and even going out of the system.
3.Enabling SELINUX: Enabling SELINUX is another way to secure your system especially a Linux Server. Selinux is a powerful security that checks and allows applications to run into the system. It won't allow any untrusted application to run into the system.
