Esse problema fornece um arquivo noodleNightmare.cpp e uma pasta chamada spaghetti contando com mais de 100 arquivos onde cada um contém apenas um palavra ou operador. O arquivo principal é formado inteiramente por #include dos arquivos da pastas, então para conseguir ler esse programa devemos substituir esses includes pela respectiva palavra/operador. Por exemplo, logo no final do arquivo na linha 853 encontramos:
```
#include "spaghetti/dhokpbpcvzqlsolslehczhyqudugoqczubzjshwlrvsmnnsbji.cpp"
#include "spaghetti/tcjbyqgtoylnpctxlgbcysapjpvqllgwzureosicdambypdocy.cpp"
#include "spaghetti/qxecmpoitqtpdyeumdbdfdyidxnbndzrnlviojinuqyxyglucp.cpp"
#include "spaghetti/nebwpbpbsokfblfcdoqptvnlakmjhnclhnqqplrsslbcomoxff.cpp"
#include "spaghetti/khgyjkyieeaomicojuzkewykloeooejjcauiubrljhpjiqrhjy.cpp"
#include "spaghetti/psotqgfoicptyfqggfkwhkjwyaqvmzmnbqjohnzwmghjnaxfve.cpp"
#include "spaghetti/znxmlwbedrctssyajamboadihyziwjpezyglhemygmjesdiycp.cpp"
#include "spaghetti/ekvebarjreidkaxcssntrzdwhvtzlfjgjszsoorotnrlrncqoa.cpp"
#include "spaghetti/fmcsuuahfryuftpsmdmyfttnnftyqjizlshaurgjlobhdxnlyi.cpp"
#include "spaghetti/nkkdzjjfvwopooqnlcivscopgvvyjvoixfpzpyajtwlxmszbcz.cpp"
#include "spaghetti/ayvgnofqweiesllskmpithbwgpzuekbthcbzmwuwfgbszwyscz.cpp"
;
#include "spaghetti/djoodumzqpuejednbfofcqohalvroroxsdeqpjtzywxopvodhx.cpp"
#include "spaghetti/gitqhgznnkvhcvwonsbljbwzfryfdjwrveupckassrafhuqudw.cpp"
#include "spaghetti/oqdoesjogfnmyorloreqdtljzzfaofqfexbqyhiishvujfmqbx.cpp"
#include "spaghetti/zzibjedgygsdnzkclvzmqyfqvaqozqpnutrefnlgmqvcmimlha.cpp"
#include "spaghetti/utvmyapvbtlkdnhqtdquzzfhcvylqifvbpnnkihdjxibxlqalw.cpp"
#include "spaghetti/ysdhhqwvzmrgwlgzoomxnbhofswnshmaxtivntzyhglvcwgfsn.cpp"
#include "spaghetti/tzcyzmfzgpwlmmwzjyztyedvtjwnafjcoebiqpllbkcgqrtlku.cpp"
#include "spaghetti/odpeswpyfiutfonuaxezaffpnvcsiualbyjpszbatalvtztiwu.cpp"
;
#include "spaghetti/gjzmlkoxjnastqhmykroyvvycsvujbspjbojqyydkfampwrujw.cpp"
#include "spaghetti/xhfvwsawrgulvmvkkxnjknpngavtbmikgmbmlbdtekqcioyyey.cpp"
```
Substituindo os includes encontramos:
```
if
(
____
==
__
)
{
cout
<<
"Congratulations, you have untangled this spaghetti!"
<<
endl
;
}
else
{
cout
<<
"Not this time!"
<<
endl
;
}
}
```
A partir disso podemos concluir que ____ ou __ é a nossa flag, então é necessário incluir a impressão dessas variáveis:
```
cout << ____ << endl;
cout << __ << endl;
```
Após compilar e executar, obtemos nossa flag:
