Show how to get the big-Oh for the following code:

void CountSort (int A[N], int range) {
// assume 0 <= A[i] < range for any element A[i] int *pi = new int[range];
for ( int i = 0; i < N; i++ ) pi[A[i]]++;
for ( int j = 0; j < range; j++ )

for ( int k = 1; k <= pi[j]; k++ ) cout << j << endl;

}

Answer #1

`Hey,

Note: Brother if you have any queries related the answer please do comment. I would be very happy to resolve all your queries.

Since there are 2 loops but, they are not nested. So, first for loop has complexity of

O(n)

Second for loop will have complexity of O(N+range)

So,

total complexity is O(N+range)

Kindly revert for any queries

Thanks.
