Word Pattern Matching
You are given a pattern string and a space-separated string s. Your task is to determine if s follows the same pattern specified by the pattern string.
In other words, there must be a one-to-one mapping between a letter in pattern and a non-empty word in s. For example, if we have:
\( pattern = \texttt{abba} \) and \( s = \texttt{dog cat cat dog} \)
the function should return True
since the mapping is consistent (\( a \rightarrow \texttt{dog} \) and \( b \rightarrow \texttt{cat} \)). Conversely, if \( s \) were "dog cat cat fish", the mapping would break and you should return False
.
Your solution should read input from stdin
and output the result to stdout
.
inputFormat
The input consists of two lines:
- The first line contains the pattern string.
- The second line contains the space-separated string s.
Both lines are non-empty.
outputFormat
Output a single line with either True
or False
(without quotes) depending on whether the string s follows the pattern.
abba
dog cat cat dog
True
