This article mainly introduces the regular expression how to match consecutive numbers, the article is very detailed, has a certain reference value, interested friends must read it!

The requirements for implementation are as follows:

Pure number

Between 5 and 7 digits

The first three are the same.

Continuous from the fourth place.

Such as the following example:

11123 # correct 22234 # correct 33345 # correct 2223456 # correct 0001234 # correct 00012345 # error: the length of this line exceeds the standard 000234 # error: bit 3 and bit 4 are not contiguous 111235 # error: bit 5 and bit 6 are not contiguous

1. Match three identical digits

(\ d)\ 1 {2}

2. Match consecutive digits

Matching consecutive numbers can be matched by zero-width assertions, of course, there is no good way, can only be enumerated, the following two lines can match 3 consecutive digits

(0 (? = 1) | 1 (? = 2) | 2 (3) | 3 (4) | 4 (5) | 5 (6) | 6 (7) | 7 (8) | 8 (9)) {2}\ d\ d ((?)
