John tells you that a certain algorithm runs in time

$O(n^3+200n),$ and Bill tells you that the same algorithm runs in

time $O(n^2).$ Choose the correct statements.

Not both John and Bill can be correct.

John's statement is more informative $($gives a better estimation of the

running time$)$

Both John and Bill can be correct

Bill's statement is more informative $($gives a better estimation of the

running time$)$
