I would say that the best option would be a multimedia card.
Answer:
O(N!), O(2N), O(N2), O(N), O(logN)
Explanation:
N! grows faster than any exponential functions, leave alone polynomials and logarithm. so O( N! ) would be slowest.
2^N would be bigger than N². Any exponential functions are slower than polynomial. So O( 2^N ) is next slowest.
Rest of them should be easier.
N² is slower than N and N is slower than logN as you can check in a graphing calculator.
NOTE: It is just nitpick but big-Oh is not necessary about speed / running time ( many programmers treat it like that anyway ) but rather how the time taken for an algorithm increase as the size of the input increases. Subtle difference.
Answer:
Explanation:
a)use order by clause for sorting
for $x in doc("books.xml")/bib/book order by xs:float($x/price) return $x/title (default sorted in ascending order)
or
for $x in doc("books.xml")/bib/book order by xs:float($b/price) descending return $b/title (sorted in descending order)
b)doc("books.xml")//book[author = 'Abiteboul']
c)for $x in distinct-values(doc("bib.xml")/bib/book/author)
return <res>
<name>{$x}</name>
<count>
{count (doc("bib.xml")//book[exists(indexof(author,$x))]) }
</count>
<res>
