Answer:
No you can not tell that recursion is ever required to solve a problem.
Recursion is required when in the problem, the solution of the input depends on the solution of the subsets of the input.
Iteration is also another form of repetitive approach we follow to solve that kind of problems.
But the difference between recursion and iteration is :
- In recursion we call the function repeatedly to return the result to next level.
- In iteration certain bunch of instructions in a loop are executed until certain conditions met.
Explanation:
For example in the Fibonacci sequence problem, to find 
, we need to compute 
and 
before that.
- In case of recursion we just call the method Fibonacci(n) repeatedly only changing the parameter Fibonacci(n-1), that calculates the value and return it.
Fibonacci(n)
1. if(n==0 or n==1)
2. return 1.
3.else
4. return( Fibonacci(n-1)+Fibonacci(n-1) )
- But in case of iteration we run a loop for i=2 to n, within which we add the value of current
and 
to find the value of 
Fibonacci(n)
1. if(n<=2)
2. result = 1
3. else
4. result1 =1 and result2=1.
5. { result = result1 +result2.
6. result1= result2.
7. result2 = result.
8. }
9. output result.
I think it's Graph Search because there isn't any graphs in Facebook. That is my opinion. I don't use social media.
Answer:
The answer is "option d".
Explanation:
When an employee is fired so, their account should be closed, and the employee records should be maintained over a certain time specified by the rules and procedures of the company. and other options can be defined as:
- In option a, It is not important to delete the user account because later on, the company would need info about that account.
- In option b, There's no need to talk to the superior of the employer.
- In option c, change the user password is not enough to update the user's password; the account should also be deleted.
In the lab, Wireshark continued to capture data in the background until the capture process was manually stopped later in the lab.
Wireshark is a packet analysis tools, it gets the information for traffic passing through a specific network node.
The smallest v groove angle that can be welded using the FCA welding process is 20 degrees. Double v joints help for buckling forces especially in welding thicker metals.
