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
substring in
str
.
Example 1:
Input: pattern ="abab", str ="redblueredblue"Output: true
Example 2:
Input: pattern = pattern ="aaaa", str ="asdasdasdasd"Output: true
Example 3:
Input: pattern ="aabb", str ="xyzabcxzyabc"Output: false
Notes:
You may assume both
pattern
and
str
contains only lowercase letters.
