    Looks like markdown code tags aren't supported, but html pre tag is.

    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)) {
        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 => {
      if (Object.values(obj).length < 2) {
      return Object.values(obj).filter(i => !Number.isInteger(i)).forEach(getSizes)
    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 {
    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.

    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.
