Positive and Negative Lookahead
Hints
Hint 1
Remeber to use 2 lookaheads to check the patterns in the string. The first lookahead is very similar to that given in the example - ‘(?=\w{3,6})’ - only the lower-number 3 is too low for our test cases, and an upper-number is completely unneccesarry. This first lookahead is only used to find a string consisting of a certain amount of characters. A second lookahead must be used to check for consecutive numerical values.
Hint 2
The second lookahead is also similar to that given in the example - (?=\D*\d) - however, this expression too must be modified to pass all test cases. Remember to specify the exact amount of numbers you want to appear consecutively.
