{ "data": { "question": { "questionId": "290", "questionFrontendId": "290", "boundTopicId": null, "title": "Word Pattern", "titleSlug": "word-pattern", "content": "

Given a pattern and a string s, find if s follows the same pattern.

\n\n

Here follow means a full match, such that there is a bijection between a letter in pattern and a non-empty word in s.

\n\n

 

\n

Example 1:

\n\n
\nInput: pattern = "abba", s = "dog cat cat dog"\nOutput: true\n
\n\n

Example 2:

\n\n
\nInput: pattern = "abba", s = "dog cat cat fish"\nOutput: false\n
\n\n

Example 3:

\n\n
\nInput: pattern = "aaaa", s = "dog cat cat dog"\nOutput: false\n
