Answer:
"ArithmeticException" is the correct answer for the above question.
Explanation:
Missing Information : The above question does not hold that "what is the output of the program".
- The above question has a class that holds the two functions one function is the main function which calls the other function in a try-catch block.
- The method function holds one run time exception which is 1/0 which is an arithmetic exception.
- It can be handle by the help of an arithmetic class object which is defined in the first catch block.
- Hence the print function of this catch is executed and prints "ArithmeticException".
Answer:
a. 118.20.210.254
Explanation:
Here are the few characteristics of Class A:
First bit of the first octet of class A is 0.
This class has 8 bits for network and 24 bits for hosts.
The default sub-net mask for class A IP address is 255.0.0.0
Lets see if the first bit of first octet of 118.20.210.254 address is 0.
118 in binary (8 bits) can be represented as : 1110110
To complete 8 bits add a 0 to the left.
01110110
First bit of the first octet of class A is 0 So this is class A address.
For option b the first octet is : 183 in the form of bits = 10110111 So it is not class A address
For option c the first octet is 215 in the form of bits = 11010111 So it is not class A address
For option d the first octet is 255 in the form of bits = 11111111. The first bit of first octet is not 0 so it is also not class A address.
It depends on what algorithm you’re using.
If you’re going item by item, you’ll be looking at O(n) or O(40000)
Give me a reply if you want to know more, such as if you did binary search what the Big O notation is
