QUESTION
Suppose n
is a BigInteger
and I want its first 5 digits. I'm thinking in 2 ways:
- Dividing
n
by 10 log10(n)-5 times (so only the first 5 digits would remain). - Get the
Substring(0, 5)
ofn
's string.
I have no idea which one is faster or if there is another option that may be better than these.
I would like to hear considerations about it before I test these options (what do you think of them, if there is something better, etc.).
...ANSWER
Answered 2021-Jun-10 at 15:11If we want to find out first 5 leading digits, we can exploit integer division:

To achieve this, just add filter for each attribute name separately:
QUESTION
While going through JCIP
, I came across the below code snippet which was considered as Immutable
. However the explanation provided makes me confused.
OneValueCache wouldn't be immutable without the copyOf calls in the constructor and getter. Arrays.copyOf was added as a convenience in Java 6; clone would also work.
Aren't the state vars
of OneValueCache
themselves Immutable
with final
and BigInteger
being itself immutable
? Why do we need to have Arrays.copyOf
if the state of OneValueCache
is already Immutable
?
ANSWER
Answered 2021-Jun-07 at 03:44The final
applies to lastFactors
, but not to the elements of lastFactors
. If the methods returned lastFactors
directly without copying it, the caller could modify the elements of lastFactors
without any problems, changing the internal state of OneValueCache
. With the copy operations, the returned arrays are copies of the final variable, and any modifications will modify the copy of the array, not the immutable instance.

QUESTION
i'm currently trying to solve a HackerRank problem, the problem in question is called Fibonacci Modified.
The method returns an int but it is expected that I will be obtaining huge values. I'm solving this problem in Java.
Here is my code
...ANSWER
Answered 2021-May-31 at 01:26You cannot, the maximum value for int is 2,147,483,647
(32 bits of value). If you need big numbers you must use the appropriate variable type.
If for some reason you want to avoid BigInteger
at all and your are not going to do any arithmetic operation later, you can always return a String
About the hackerrank problem, just modify the result variable type to BigInteger
. Actually, they seem to be aware of the 32/64 bits issue... they are using a String
value to prevent it.
There's no reason to keep the whole code-template structure. They just care about input/output. You are allowed to modify EVERYTHING but those two things.
This is their output (here you can see their output is expected to be a String
):

I have following models defined:
...ANSWER
Answered 2021-May-30 at 08:16db.query(models.Data).all()
returns an array of Data
objects. So you can define a custom property on the Data
class to extract names from attributes relationship:
