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
, we need to compute  and
 and  before that.
 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 and to find the value of 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.
 
        
             
        
        
        
Answer:
The correct answer to the following question will be Option D (Cloud service developer).
Explanation:
- Developers are usually individuals who layout and build applications or websites such as web or software systems. They would be known as app or web developers in this regard. In the sense that they still build and maintain things, a software developer is quite similar, however-and here's the deciding factor-this is achieved on virtual clouds.
- It is the responsibility of the cloud service developer to design and build cloud elements and products, as well as to check and validate services.
Therefore, Option D is the right answer.
