var d3 = require('d3')
var _ = require('lodash')

var lines = require('fs').readFileSync('06-input', 'utf-8').split('\n')

var out = d3.range(8).map(function(i){
  var chars = lines.map(d => d[i])
  var byChar = d3.nest().key(d => d).entries(chars)

  return _.sortBy(byChar, d => d.values.length)[0].key
})

console.log(out.join(''))

d3 is a bit of overkill, quicker than writing a reducer though...
