Hi, Is anyone having the code to implement PCA and calculate the time complexity of PCA in terms of Big 0,omega or theta? For eg: What is the time complexity if we take 50,100,150,...training images? Is there an
⚠️ Be careful with function calls. You will have to go to the implementation and check their run time. More on that later. Conditional Statements Very rarely, you have a code without any conditional statement. How do you calculate the time complexity? Remember that we care about the wo...
So, if I run a nested loop ofninside the loop ofqthen the time complexity would beO(q*n)that means(10^5)*(10^5)which is10^10. The problem has a6 secondstime limit. But my solution gaveTLE.My Submission Where do I have to optimize and how can I calculate such a complex scenario...
So the asymptotic time complexity for the above code is O(N), which means that the above algorithm is a liner time complexity algorithm.There you have it, now you know how to calculate the time complexity of a simple program.Comments

How to calculate “hard” runtime complexity? 在技术面试中,准确说出一个解法的runtime complexity(算法时间复杂度)是一个非常重要的点。考虑到对于算法时间复杂度的理解是CS领域的基础,因此这类问题,回答对了往往那不加分,但是回答错误往往是致命的,因此大家不能掉以轻心。
In your first example, how many times will line 4 be executed? Write it as a function of n. Whatever your formula is, that's the time complexity. Assuming k starts at 1, the first time through k becomes 2. The second time through it becomes 4. The ...

Big O notation expresses the run time of an algorithm in terms of how quickly it grows relative to the input(this input is called “n”). This way, if we say for example that the run time of an algorithm grows “on the order of the size of the input”, we would state that as ...
Customer lifetime value (CLV) measures the total net profit a business can expect to earn from a customer throughout their entire relationship with the brand.
