I am trying to solve [SPOJ] problem. I have used sieve of eratosthenes algorithm. But it is still slow when input is in range of 104
import math
no_of_cases = int(input())
for i in range(no_of_cases):
x = input().split(" ")
a = int(x[0])
b = int(x[1])

Definition of util::any
[Taken from the standard's description of std::any]
A discriminated type that can contain values of different types but does not attempt conversion between them, i.e. 5 is held strictly as an int and is not implicitly convertible either to "5" or to 5.0. This indifferenc...
I am reading a signal off of a meter using a managed C# wrapper on a C++ object. In order to calculate the value of the meter, I need to determine the length of time from when the signal goes from 0 to 1 then back from 1 to 0. So, my code looks like the following:
var sw = new StopWatch();
var...
How can I make this little program works little faster?

for (int i = 0; i < a.len...
I have a question regarding the performance of my python program. The part which is written down is very essential and I already increased the performance with numpy. I would like to know if it is possible to make this part even faster? A 10x speed up would already be nice..

When users log in to our website, we store some information in a session to retrieve it across the site. We created a few wrappers to help with data retrieval/storage to lessen duplication of code.
I'm trying to redesign it as I don't like how the UserModel is written. I believe it's dangerous w...
