WebMar 7, 2024 · Simply plugging in random numbers does not suffice to calculate Big-O. Big-O is more so about long term growth, so it is possible to get an intuition if you plug in really large numbers and/or plot the functions, but you can not 100% depend on this method since there is always the question about whether or not you went out far enough. WebWe use big-O notation for asymptotic upper bounds, since it bounds the growth of the running time from above for large enough input sizes. Now we have a way to …
