Mid/SeniorEnumeration
Sequential Digits
An integer has sequential digits if and only if each digit in the number is one more than the previous digit.
Return a sorted list of all the integers in the range [low, high] inclusive that have sequential digits.
Example 1
Input
low = 100, high = 300Output
[123,234]The sequential-digit integers between 100 and 300 inclusive are 123 and 234.
Example 2
Input
low = 1000, high = 13000Output
[1234,2345,3456,4567,5678,6789,12345]The sequential-digit integers between 1000 and 13000 inclusive are 1234, 2345, 3456, 4567, 5678, 6789, and 12345.
Constraints
- 10 <= low <= high <= 10^9
