Answer: True
Explanation:
Subset sum problem and Knapsack problem can be solved using dynamic programming.
In case of Knapsack problem there is a set of weights associative with objects and a set of profits associated with each object and a total capacity of knapsack let say C. With the help of dynamic programming we try to include object's weight such that total profit is maximized without fragmenting any weight of objects and without exceeding the capacity of knapsack, it is also called as 0/1 knapsack problem.
Similar to knapsack problem, in subset sum problem there is set of items and a set of weights associated with the items and a capacity let say C, task is to choose the subset of items such that total sum of weights associated with items of subset is maximized without exceeding the total capacity.
On the basis of above statements we can say that subset sum problem is generalization of knapsack problem.
num1 = float(input("Enter the first number: "))
num2 = float(input("Enter the second number: "))
operation = input("Which operation are you performing? (a/s/m/d) ")
if operation == "a":
print("{} + {} = {}".format(num1, num2, num1+num2))
elif operation == "s":
print("{} - {} = {}".format(num1, num2, num1-num2))
elif operation == "m":
print("{} * {} = {}".format(num1, num2, num1*num2))
elif operation == "d":
print("{} / {} = {}".format(num1, num2, num1/num2))
I hope this helps!
Answer:
A. Detecting network attacks and scans
Explanation:
Honeynet
It is a network , which is set up with the intentional vulnerabilities , in order to invite the attack , in order to determine and study the activities of the attacker .
The Honeynet is composed of one or more honey pots , which are just the computer systems , which act as a bait to trap the people who , tries to hack or penetrate into other's computer system .
Hence ,
The correct option is Detecting network attacks and scans .
Answer:
b) Plus sign
Explanation:
The plus sign or addition operator (+) accomplishes concatenation. This is a greatly used in the Java's output Statement to combine values coming from different data types into a formatted output
consider the code snippet below which uses concatenation to output information about an individual
public class Name {
public static void main(String[] args) {
int age =18;
String name = "John";
System.out.println("His name is "+name +" and his age is "+age);
}
}
The + operator has been used to concatenate the int value age and the String value stored in name to the output
After I have changed her password, all I will need to do is select the “User must change password at next logon” option. This option will prompt her to log on to her PC using the password I assigned to her.
Explanation
An active Directory on most Domain Controllers gives you access to add users, disable accounts, change password, and various other tasks. Assuming that everything is setup, I am just going to go to my Windows Server Manager dashboard of my Domain Controller. While I am at my dashboard, I will click on tools and then drop down to the Active Directory Users and Computers to locate my desired user who seems to have been locked out.
Once the user has been identified, I will simply need to right click on the account and select “reset password”. A small dialog box with a list of cool security options will pop up. I will be required to reset it to something simple and default and make sure to select the “User must change password at next logon” option.
What this means is that the user who is locked out, upon logging back in, will be prompted to enter the password I gave them first as default but then will immediately be asked to change the password to something new. We do not see options A and B a lot in the real world. It is best practice not to select these options
