What is the f(n) runtime of the following pseudocode: sum-0 for a = n/2 downto 1 for b-1 t increment sum by b explain: exactly what is wrong with the following diagram why it is incorrect how to fix it np np- complete

The diagram part of the question is incomplete but the mathematical part has been solved below for you . However when the diagram will be attached it will be answered too.

Following is the solution for the Time complexity/ Run Time:

Given that:

A = N/2 to 1

B = 1 to 4N

By summation:

Time Complexity = Lower bound of A * Upper Bound of B

Time Complexity = (N/2) * (4N)

By simplifying:

Time Complexity = N * 2N

Time Complexity = 2N^2

Hence the runtime f(n) for given pseudocode will be 2N^2

i hope it will help you!

okay, so i know we just goofed around in that chat, but ive been like genuinly depressed, like medically depressed for almost 4 years now. i had my first panic attack when i was 8. i woke my mum up and told her i felt like i was in a dream. like i was a goldfish in a bowl, looking at all these things going on around me and feeling . tiny. wort hless. and i now am now 17 y/o. i still feel those emotions daily. life used to go by so quick.like every day i would wake up and just like want to go back to bed cause i always felt like i was in the wrong place. i guess looking back, i was in the wrong state of mind. i took a expensive like nice trip to whyoming with my grandfather and ha ted it. like idk why. i would have loved it now, but i found myself writing in a journal everyday because i would forget what happened the day before, couldnt remember what i ate for like the previous meal. just my memory left me for the week i was there. worst feeling ive ever experienced.

you may need to email for some tech support. : )
