I know how I can solve the problem, but what is the flag exactly? It's not explained how the flag should be formulated.

I got the answer but what format am i supposed to submit it in????

This is a really great challenge in my opinion.

I used c++ and the hardest part was to put space int the end of every line.

nice programming, using python code

I used regex with node.js ```const fs = require('fs') var text = fs.readFileSync('./data.dat','utf8')

function count0(bin){ var arr = bin.match(/(0)/g); return arr ? arr.length : 0; } function count1(bin){ var arr = bin.match(/(1)/g); return arr ? arr.length : 0; }

var binArray = text.split('\n') var succArray = []

binArray.forEach((bin) => { var zeros = count0(bin); var ones = count1(bin); if(ones % 2 == 0){ succArray.push(bin); } else if(zeros % 3 == 0){ succArray.push(bin); } }); console.log(succArray.length)```
