Which of the following shows a list of big-oh running times in order from slowest to fastest?

o(1), o(n), o(n2), o(logn), o(2n)

o(1), o(n), o(n3), o(2n), o(n! )

o(logn), o( o(n2), o(n3), o(2n)

o( o(2n), o(n2), o(n), o(logn)

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.

a software system that is used for viewing and creating hypertext is a hypertext system.

i hope this .
