something other than secret..

this should be top solution

ERROR should say that it can only do addition with integers, since that's what you're testing for.

Really, your code works fine with 1044388881413152506691752710716624382579964249047383780384233483283953907971557456848826811934997558340890106714439262837987573438185793607263236087851365277945956976543709998340361590134383718314428070011855946226376318839397712745672334684344586617496807908705803704071284048740118609114467977783598029006686938976881787785946905630190260940599579453432823469303026696443059025015972399867714215541693835559885291486318237914434496734087811872639496475100189041349008417061675093668333850551032972088269550769983616369411933015213796825837188091833656751221318492846368125550225998300412344784862595674492194617023806505913245610825731835380087608622102834270197698202313169017678006675195485079921636419370285375124784014907159135459982790513399611551794271106831134090584272884279791554849782954323534517065223269061394905987693002122963395687782878948440616007412945674919823050571642377154816321380631045902916136926708342856440730447899971901781465763473223850267253059899795996090799469201774624817718449867455659250178329070473119433165550807568221846571746373296884912819520317457002440926616910874148385078411929804522981857338977648103126085903001302413467189726673216491511131602920781738033436090243804708340403154190336 ?

I am skeptical of my rust code as I am new but I don't get the python error it's how is it my code that gives a time out I tested it in my pc and it works perfectly fine.

No problem :)

Rust and Python fork fixing a problem in reference solution.

OK, thanks for your work, sorry the forms. With the problem I have learned a lot about iterators, jaja. Thanks for that.

You are right, there is a problem. I've just published a new fork, I hope it's approved soon.

Good :) Now you know you need to find a radically different approach. Maybe it's better to focus more on the representation that on the number.

What needs to be fixed is your code. In Rust, line 6 causes an error; don't you guess what's happening? Your code in Python times out, it's your problem; translation was published two days ago, and 35 persons solved it without complaining.

Julia translation

I think that with that input, it will take a long time to be solved...

I tried with the input 123416523 and it took (37.97 secs, 74,454,731,984 bytes) to get the solution, which by the way is: 68961984

I see that this problem has exponential time to be solved, related to how big the input is...

• For example:
  • if the input is 12341652, it takes (3.81 secs, 6,917,976,752 bytes), but
  • an input which is one digit greater (fo example: 123416523) makes the solution time to go to (37.97 secs, 74,454,731,984 bytes)
