design an application that receives integer input from the user and then the application determinens the sum of all the digits in the integer
using Python
Well, another option is:
int sum = 0;
while (value != 0)
{
int remainder;
value = Math.DivRem(value, 10, out remainder);
sum += remainder;
}
BigInteger has a DivRem method as well, so you could use the same approach.
Note that I've seen DivRem not be as fast as doing the same arit...
I haven't done any research into how you actually write a genetic algorithm, so this is my best guess. What I'm really curious to know is two-fold:
Have I created a genetic algorithm?
If I have, how can I continue to explore the subject more?

The primary purpose of this program is to practice catching if the user enters data that does not correspond to expected input. Note if the user enters there name as "123", this is valid as it can be used as an identity, however if the user enters only spaces (i.e. " ") or just a newline char ...
Here's yet another version of the retry strategy helper. This time I added a TryState to it.
I think it shouldn't just try to brute force execute something but it's also good to know if it's always failing and if it succeeds then after which timeout/repetition.
There maybe a situation when it s...
