  Definitely a bit of a jump between yesterday and today's. Wasted a fair bit of time trying to recursively calculate the aggregated directory sizes after building the file system.

  Once I calculated the dir sizes as I went along building the file system, it was much easier.

  Solution >

  let fs = {}
  let dirHistory = []
  let currentDir = fs
  
  arr.forEach(i => {
    if (i === '$ cd ..') {
      currentDir = dirHistory.pop()
    } else if (/\$ cd [a-z]+/.test(i)) {
      dirHistory.push(currentDir)
      let dirName = i.match(/[a-z]+/g)[1]
      currentDir = currentDir[dirName]
    } else if (/dir [a-z]+/.test(i)) {
      let dirName = i.match(/[a-z]+/g)[1]
      currentDir[dirName] = { size: 0 }
    } else if (/[0-9]+/.test(i)) {
      let size = Number(i.match(/[0-9]+ /)[0].trim())
      currentDir.size += size
      dirHistory.forEach(histItem => {
        histItem.size += size
      })
    }
  })
  
  
  let sizeArr = []
  let getSizes = obj => {
    sizeArr.push(obj.size)
    if (Object.values(obj).length < 2) {
      return
    }
    return Object.values(obj).filter(i => !Number.isInteger(i)).forEach(getSizes)
  }
  
  getSizes(fs)
  sizeArr.filter(i => i <= 100000).reduce((a, i) => a + i, 0)

  Ragleys look to be just what I'm after (sorry @ltc!) - will DM.

  Made the most of being woken up at 5.45am today.
  Do like the ones where part 2 is the same as part 1, but makes you rewrite a naive/quick and dirty solution to part 1.

  let n = 14
  let i = 0
  let found = false
  
  while (!found) {
    if (new Set(str.slice(i, i + n)).size === n) {
      found = true
    } else {
      i++
    }
  }
  
  console.log(i + n)

  Cheers - interested in the salsa bend deluxe 27deg and ragley back sweep - which ones are the Ragleys in the pic?

  What are you after for each?

  Moved some bits over from my pump track bike which I can't use at the moment, to a £50 frame I got on eBay, to build something cheap and utilitarian but nice to ride.

  Frame is 1650g(!) and the whole thing is around 11kg at the moment. Quite happy with the £70 8 speed Microshift drivetrain.

  Planning to get some thinner, slightly lighter tyres (as nice as cornering on 2.3" semi-slicks is) and some more swept bars, to make it more suited to longer distances.

  Interested in the mech, cassette, shifter and brakes in case you end up splitting.

• FS MINT 1995 Cannondale F700 now £300

  This has to be worth way more than £300 to the right person, surely... maybe eBay for further reach?

  Either way, best to update the thread title to the new price though, so more people see what a bargain it is.

  GLWS!
