lo.logic – A question related to the conjectures of ABC and Goldbach

Consider the even number $ 128 = $ 2 ^ 7 that would satisfy the ABC-Conjecture requirements according to the two distinct examples below:

  • $ (1) $ $ 3 + 5 ^ 3 = $ 2 ^ 7
  • $ (2) $ $ 31 + 97 = $ 2 ^ 7

But in $ (1) $, $ rad (abc) <c $ in $ (2) $, $ rad (abc)> c $. (Note that $ 128 is an even number which is not a counterexample of Goldbach's conjecture, and there is always an infinite number of such non-counterexamples).

It seems then in general, if we only know that $ c $ is same and that it exists $ a $ and $ b $ such as $ (a, b, c) $ would form an ABC-Conjecture triplet, then it would be impossible so invalid to claim $ rad (abc) <c $, or $ rad (abc)> c $.

Would it be true?

Check which numbers meet the condition [A*B*C = A! + B! + C!]

Should I use recursion for factorial function?

int Factorial (int n)
{
int k = 1;
for (int i = 1; i <= n; ++ i)
{
k = k * i;
}
returns k;
}

How can I do this in one loop instead of the 3 while loops?

int main ()
{
int a = 1;
int b = 1;
int c = 1;
int Fact1;
int Fact2;
int Fact3;
while (a <11)
{
Fact1 = Factorial (a);
while (b <11)
{
Fact2 = Factorial (b);
as long as (c <11)
{
Fact3 = Factorial (c);
cost << s << ":";
int LHS = Fact1 + Fact2 + Fact3;
if (LHS == a * b * c)
{
cost << "Pass:" << "" << << << << << << << << c << endl;
}
other
{
cost << "Fail" / * << "" << Fact1 << "" << Fact2 << "" << Fact3 * / << endl;
}
c ++;
s ++;
}
c = 1;
b ++;
}
b = 1;
a ++;
}
returns 0;
}

Also, I would like some variable naming tips.

The cleanest way to take a[b[c]]has a[b][c]

As stated in the title, I'm looking for the fastest way to transform a[b[c]] in a[b][c]. I am sure that there must be a convenient way that I have neglected.

In my case a, b, and c can be any expression with any complicated internal structure that they like.

bitcoinabc – Import / Export Portfolio vi bitcoin-cli. Bitcoin abc node

I would like to move my bitcoin money wallet from one server to the other with the help of the cli.

Server 1: bitcoin abc: 0.17.2.
Server 2: bitcoin abc: 0.18.0

I did the following:

  1. ran the command: backupwwallet "myfile.dat" on server 1 successfully.
  2. copy the "myfile.dat" on the server 2.
  3. Enter the command: importwallet "myfile.dat".

The following error message is displayed when I try to import the wallet:

error code: -8
Error message:
Can not open the dump file of the wallet.

I've also tried replacing the stop node on server 2 and copy the wallet.dat file to the other server and then restarting the wallet on server 2.
I get the following error in the logs:

CDBEnv :: Open: LogDir = /home/cryptodaemon/ .bitcoincash / database ErrorFile = / home / cryptodaemon / .bitcoincash / db.log
2018-09-09 07:48:21 Failed to change the name of wallet.dat to wallet.dat.1536479301.bak.

How can I move the portfolio from one server to another?
Could someone give me some guidance in this regard?

lo.logic – Is this $ abc $ conjecture true of natural numbers?

Here, the notation $ abc $ is identical to $ (abc) $ and is the name of a conjecture that is (so to speak) a reduction from the familiar $ abc $ conjecture. This $ abc $ the conjecture would be described below.

Let $ P $ be the set of prime numbers defined by the following:

  1. If there is an even number $ e $ more than two and is do not a sum of two prime numbers, then the prime number $ p $ which is the greatest number less than $ e $ is called a first$ & $ number. For example, if $ 10 $ were not a sum of two prime numbers then the first $ 7 $ would have to be a first$ & $ number.

  2. $ P = {p | text {$ p $ is a prime number but not a prime number & # 39; $ number} } $

    Naturally $ P $ is not empty since, for example, $ 2, 3, 5, 7 in $ $ P $.

the $ abc $ the conjecture is then defined as being the familiar $ abc $ conjecture, except that all the prime numbers concerned must necessarily be in $ P $.

Is $ abc $ true guess of natural numbers?

Virus warning in Bitcoin [cash] ABC client?

I've tried to download Bitcoin Cash's ABC wallet from the Bitcoincash official website.

If I download zip on my computer and download it to the VirusTotal site, it says 11/62 positives.
If I go to the VirusTotal site and that I enter the zip URL to scan, it means that it is clean.
The sum SHA-256 is also different.

Is this normal?
Maybe someone else can test? : /

https://download.bitcoinabc.org/0.17.2/win/bitcoin-abc-0.17.2-win64.zip

edit: the SHA256 is identical, I originally thought that it was different, maybe I compared too much at once, the main problem (warnings) remains.

clean, of url
not clean, from the downloaded zip
