Write

function wordPattern(pattern, str)

WordPattern(string pattern, string str)

word_pattern(pattern, string)

word_pattern(pattern, string)

that given a pattern and a string str, find if str follows the same sequence as pattern.

For example:

wordPattern('abab', 'truck car truck car') === true
wordPattern('aaaa', 'dog dog dog dog') === true
wordPattern('abab', 'apple banana banana apple') === false
wordPattern('aaaa', 'cat cat dog cat') === false

WordPattern("abab', "truck car truck car") == true
WordPattern("aaaa", "dog dog dog dog") == true
WordPattern("abab", "apple banana banana apple") == false
WordPattern("aaaa', "cat cat dog cat") == false

word_pattern('abab', 'truck car truck car') == True
word_pattern('aaaa', 'dog dog dog dog') == True
word_pattern('abab', 'apple banana banana apple') == False
word_pattern('aaaa', 'cat cat dog cat') == False

word_pattern('abab', 'truck car truck car') == true
word_pattern('aaaa', 'dog dog dog dog') == true
word_pattern('abab', 'apple banana banana apple') == false
word_pattern('aaaa', 'cat cat dog cat') == false

Note: Each letter in the pattern stands for a distinct word
