Answer:
Option A(True) is the correct answer for the above question.
Explanation:
- The flowchart is used to give the solution of a problem through the diagram in a step by step processor. It helps the user to understand the solution easily. For diagram, it uses many types of symbols that are fixed for every sequence just like An oval symbol represents the start and end of the flowchart which is fixed for every flowchart.
- So for the decisions in a flowchart, the diamond symbol is used which is to make the decisions and it has two sides-- one is true and the other is false.
- The decisions are used also to represent the loop structure which is also called the repetition structure because the loop is controlled by the help of decisions so the diamond box is also used for the loop
- The above question-statement says that the decisions-controlled is used for the loop and for the decisions which are true because it is also described above.
the answer is 5,000 hours.
I recommend you post these kind of questions in the mathematics section
Answer:
Explanation:
( n cards are there initially )
we pick out the first card in random it takes n-1 comparisons to figure out
its Equivalence card - n-1 steps
Two cards have been eliminated ( this leaves us with 2 and n-2 cards)
we pick out the 2nd card in random it takes n-3 comparisons to figure out
its Equivalence card - n-3 steps
we continue to do this.. till all cards are exhausted ( leaves us with 2
and n-4 cards again)
the last comparison will
have
- n-(n-3)
the sum of all these steps - (n-1) + (n-3) + (n-5) + .........+
(n-(n-3))
if you draw this in the form of a tree.
n - n
2
n-2 - n
2
n-4 - n-2
2
n-6 - n-4
2
n-8 - n- 6
the height of the tree will be log n , sum @ each level is at most n
Answer:
Motivation? The search problem.
Sorting algorithms: insertion sort, shellsort, heapsort, mergesort, quicksort, bubblesort
At the very least, "general purpose" sorting algorithms require O(n log n) comparisons
Explanation:
F socket refers to an open TCP connection, the connection is closed. If a stream socket is closed when there is input data queued, the TCP connection is reset rather than being cleanly closed. The descriptor of the socket to be closed
To close the socket you need to call shutdown() first and then close(), and shutdown takes an argument
