Answer:
The given statement is False.
Explanation:
- Needs Met Rating of a result show us that how much the result is fulfilling the query of the user. The greater the needs met rating is, the greater the satisfaction of the user is.
- If a page has high quality then it can or can not be useful for the user.
- If the page has high quality as well as high needs met rating then it is best for the user.
- If the page has high quality and has low needs met rating that means it is not relevant to the query so not useful for the user.
- Thus, it is concluded that high quality pages in a task shouldn't all get the same needs met rating rating rather need met rating is dependent upon the relevancy and usefulness of the result to the need and query of the user.
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.
