Suppose that a computer can run an algorithm on a problem of size 1,024 in time t. We do not know the complexity of the algorith
Setler79 [48]

Answer:

Time Complexity of Problem - O(n)

Explanation:

When n= 1024 time taken is t. on a particular computer.

When computer is 8 times faster in same time t , n can be equal to 8192. It means on increasing processing speed input grows linearly.

When computer is 8 times slow then with same time t , n will be 128 which is (1/8)th time 1024.

It means with increase in processing speed by x factor time taken will decrease by (1/x) factor. Or input size can be increased by x times. This signifies that time taken by program grows linearly with input size n. Therefore time complexity of problem will be O(n).

If we double the speed of original machine then we can solve problems of size 2n in time t.

Urgent. I will mark you brainliest. explain why cyber warfare is a real threat.​
stellarik [79]

Answer: Cyber warfare is a real threat since being able to hack another computer especially a countries computer with lots of info in their weaknesses can lead to their downfall. Since they can even possibly if their skilled enough hack their entire data base system and leak it to the public and that wouldn't be good for them not in a single possible way. That's the reason it's dangerous not only that but also because they can access their servers; which can let them access anything online from the whole country including banking information military info which can let them know which area there gonna go to next equipment there gonna bring and where they're gonna launch missiles, bombs, even nukes if they decide to launch one. And being able to hijack the computer that launches the nukes can make the hacker launch the nuke to a different place or launch the nuke on the country trying to launch the nuke.
