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.
Answer:
Legend
Explanation:
In English language, a legend can be defined as a traditional narrative or story that is written about a particular person or past events and it's likely to either be a myth or historical facts. Thus, a legend is sometimes an unrealistic story or narration that describe a particular person or an extraordinary event that occured in the past. Also, it's a story about a particular figure, past human events or actions whose origin is unknown, unproven and undocumented in real history
Additionally, the word "legend" was derived from the Latin word "legendus" which simply means something which should be read.
Hence, the most appropriate word to complete the sentence is a legend because there are no proven and documented or written records about how Bolster the Giant terrorised the people of Cornwall. Thus, the complete mythical sentence is then written as;
"According to legend, Bolster the Giant terrorised the people of Cornwall."
Answer:
If there is already a table in word document, clicking it should calls the table to want to show up in the top ribbon
Explanation:
I just did it!
Answer:
The modified program is as follows:
user_val = int(input())
cond_str = 'non-negative'
if user_val < 0:
cond_str = 'negative'
print(user_val, 'is', cond_str)
Explanation:
This gets input for user_val
user_val = int(input())
This initializes cond_str to 'non-negative'
cond_str = 'non-negative'
If user_val is less than 0
if user_val < 0:
cond_str is updated to 'negative'
cond_str = 'negative'
This prints the required output
print(user_val, 'is', cond_str)
