=== About [[EditStepLadders]] ===&lt;br /&gt;
편집 단계(edit step)란 어떤 단어 x에서 다른 단어 y로의 변환을 뜻하는데, 이때 x와 y는 어떤 사전에 있는 단어며 한 글자를 추가하거나 삭제하거나 바꿈으로써 x를 y로 변환할 수 있어야 한다. 예를 들어 dig에서 dog로, 또는 dog에서 do로 변환하는 것은 모두 편집 단계라고 할 수 있다. 편집 단계 사다리(edit step ladder)란 사전 순서대로 정렬된 w&amp;amp;lt;sub&amp;amp;gt;1&amp;amp;lt;/sub&amp;amp;gt;,w&amp;amp;lt;sub&amp;amp;gt;2&amp;amp;lt;/sub&amp;amp;gt;,...,w&amp;amp;lt;sub&amp;amp;gt;n&amp;amp;lt;/sub&amp;amp;gt;이라는 단어들을 뜻하는데, 이때 1에서 n-1까지의 모든 i에 대해 w&amp;amp;lt;sub&amp;amp;gt;i&amp;amp;lt;/sub&amp;amp;gt;에서 w&amp;amp;lt;sub&amp;amp;gt;i+1&amp;amp;lt;/sub&amp;amp;gt;로 넘어가는 변환은 편집 단계여야 한다.&lt;br /&gt;
&lt;br /&gt;
어떤 사전이 주어졌을 때 편집 단계 사다리의 최대 길이를 계산하는 문제를 풀어보자.&lt;br /&gt;
&lt;br /&gt;
=== Input ===&lt;br /&gt;
프로그램에 사전이 입력되는데, 소문자로 된 단어들이 한 줄에 하나씩 사전 순서대로 입력된다. 어떤 단어도 16글자를 넘어가면 안 되며, 사전에 들어갈 수 있는 단어의 개수는 최대 25,000개다.&lt;br /&gt;
&lt;br /&gt;
=== Output ===&lt;br /&gt;
가장 긴 편집 단계 사다리에 들어있는 단어의 개수를 나타내는 정수 한 개를 출력한다.&lt;br /&gt;
&lt;br /&gt;
=== Sample Input ===&lt;br /&gt;
{{| cat&lt;br /&gt;
dig&lt;br /&gt;
dog&lt;br /&gt;
fig&lt;br /&gt;
fin&lt;br /&gt;
fine&lt;br /&gt;
fog&lt;br /&gt;
log&lt;br /&gt;
wine |}}&lt;br /&gt;
&lt;br /&gt;
=== Sample Output ===&lt;br /&gt;
{{| 5 |}}&lt;br /&gt;
