Build a key out of 4 fields
key = $2$3$4$5
Check if this key has been seen before
if (seen[key] == "")
    seen[key] = $1
This means:
✔ If this exact combination of fields 2+3+4+5 has NOT been seen before
Store field1 as the first ID associated with this combination.
✔ If it

# 公式用語

ここで言う公式用語は、RFCやIANA・ICANNなどで一般的に使われている用語とする。  

## ドメイン

`example.com` `com` `example.co.jp` `co.jp` `jp` のように、ドットで区切られた階層構造のこと。  
`example.co.jp` だけがドメインじゃなくて、 `co.jp` `jp` `com` もドメインと呼ぶ。  

## ルートドメイン

`example.com.` `com.` `example.co.jp.` `co.jp.` のように、本当はドメインの最後についている「.」のこと。  
最後の「.」以外はドメインではなく、ただの区切り文字で全く意味が違うので注意。  
ちなみに、例えば `example.com.` の場合 `com` はあくまで `com` であって `.com` などではないし、 `example` も `example.` ではない。  

## ラベル

`example.co.jp` でいうと `example` `co` `jp` と

# move all files
find . -type f -exec bash -c 'mkdir -p "${1%/*}/$(date -r "$1" "+%Y")"; mv "$1" "${1%/*}/$(date -r "$1" "+%Y")/"' _ {} \;
# copy files
find . -type f -exec bash -c 'mkdir -p "${1%/*}/$(date -r "$1" "+%Y")"; cp "$1" "${1%/*}/$(date -r "$1" "+%Y")/"' _ {} \;

## Entry Syntax
```00000004 Install-map entry missing component key in populate [l:COMPONENT_NAME_LENGTH]'COMPONENT_NAME' [l:COMPONENT_VERSION_LENGTH]```

## Meaning
The ```identity``` name is missing under ```HKEY_LOCAL_MACHINE\COMPONENTS\DerivedData\VersionedIndex\...\ComponentFamilies\COMPONENT_NAME```.

## Entry Syntax
```00000003 PopulateComponentFamilies ignoring identity-less key [l:COMPONENT_NAME_LENGTH]'COMPONENT_NAME'```

## Meaning
The ```identity``` name is missing under ```HKEY_LOCAL_MACHINE\COMPONENTS\DerivedData\VersionedIndex\...\ComponentFamilies\COMPONENT_NAME```.

/**
 * @param {number} k
 * @return {number}
 */
var smallestRepunitDivByK = function(k) {
    // Step 1: Handle impossible cases
    // Any number made only of '1's is odd and not divisible by 2 or 5.
    // So if k has a factor of 2 or 5, return -1 immediately.
    if (k % 2 === 0 || k % 5 === 0) {
        return -1;
    }

    // Step 2: Initialize variables
    // remainder will track (current number % k) without building the full number.
    // length will track how many '1's we've added so
