If the three operations were combined, O(logN) + O(N) * O(logN) + 1, the overall algorithm cost would be:________
KiRa [710]

Answer:

D. O(NlogN)

Explanation:

The computation of the overall algorithm cost is as follows:

Given that

O(logN) + O(N) × O(logN) + 1

In the case of complexity we considered the high order that dominates the other terms

Thus, that term would be  

O(N) × O(logN)

It could be rewrite as

O(NlogN)

Hence, the correct option is D.

All the other options are wrong

2. Consider the two-dimensional array A: int A[][] = new int[100][100]; where A[0][0] is at location 200 in a paged memory syste
bogdanovich [222]

Answer:

Check the explanation

Explanation:

An integer (int) is of two different bytes and each page has 200 bytes in length. What this means is that each row of array A (100 int) will fits perfectly in a page.

(a) For the initial or first array-initialization loop, one column is processed at a time, so a page fault will be generated at every inner loop iteration, with a total of 100*100=10,000 page faults.

(b)  And when it comes to the second array-initialization loop, one row is processed at a time, and a page fault is generated at every outer loop iteration, with a total of 100 page faults.

Hence second array-initialization loop, has better spatial locality.
