________ is the newest social network from Google

A random access file is organized most like a(n):

a. Array. b. Object. c. Class. d. Pointer.

The instruction function f(n) = 4n + 3 lg n belongs to the O( n ) time complexity because:

A. the n term is the first term in the function B. there is only an n term and a lg n term, and there can not be a O( lg n ) time complexity C. the lg n term is absorbed into the n term for the time complexity D. This statement is false. This function belongs to the O( n + lg n ) time complexity.
