This issue will happen mostly if cellular network will not be down, or suppose if cellular network is down mostly, or it will be rainy or a current cutoff issue might be occurred.
<u>Explanation:</u>
The following step to be made for trouble shoot his phone when cellular network is down.
1. Restart the mobile:- After restarting kindly check mobile connectivity.
2. Check for mobile air plane mobile and make sure the mobile phone is not in air plane mode.
3. Check the income and outgoing vapidity.
4. Switch off the mobile, Remove service provider sim card from mobile and reinsert the sim card and start the mobile.
5. Still connectivity problem, either contact the service provider or replace with new sim card.
Someone can install an operating system by disk or removable storage media.
Disk being floppy, tape or commonly a DVD.
Removable storage being a USBdrive.
Big-O notation is a way to describe a function that represents the n amount of times a program/function needs to be executed.
(I'm assuming that := is a typo and you mean just =, by the way)
In your case, you have two loops, nested within each other, and both loop to n (inclusive, meaning, that you loop for when i or j is equal to n), and both loops iterate by 1 each loop.
This means that both loops will therefore execute an n amount of times. Now, if the loops were NOT nested, our big-O would be O(2n), because 2 loops would run an n amount of times.
HOWEVER, since the j-loop is nested within i-loop, the j-loop executes every time the i-loop <span>ITERATES.
</span>
As previously mentioned, for every i-loop, there would be an n amount of executions. So if the i-loop is called an n amount of times by the j loop (which executes n times), the big-O notation would be O(n*n), or O(n^2).
(tl;dr) In basic, it is O(n^2) because the loops are nested, meaning that the i-loop would be called n times, and for each iteration, it would call the j-loop n times, resulting in n*n runs.
A way to verify this is to write and test program the above. I sometimes find it easier to wrap my head around concepts after testing them myself.
Indeed, this is to be true as software is to programs and applications(apps) hardware is to physical computers such as hard drive, SSD, motherboard, ram, graphics card, ect...
Answer:
hierarchy chart
Explanation:
Based on the information provided within the question it can be said that in this scenario programmers usually use a hierarchy chart. This is a chart that shows the relationship that exists between various different modules that are able to call on another. Therefore showing the programmers the organization of the entire overall program.
