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

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

Example 1:


Input: pattern = "abba", str = "dog cat cat dog"
Output: true

Example 2:


Input:pattern = "abba", str = "dog cat cat fish"
Output: false

Example 3:


Input: pattern = "aaaa", str = "dog cat cat dog"
Output: false

Example 4:


Input: pattern = "abba", str = "dog dog dog dog"
Output: false

Notes:
You may assume pattern contains only lowercase letters, and str contains lowercase letters separated by a single space.
