An integer is defined to have sequential digits if each digit in the number is exactly $1$ greater than the digit preceding it.

Given two integers low and high, return a sorted list of all integers in the inclusive range $[$low, high$]$ that have sequential digits.

Constraints:

• $10 \leq$ low $\leq$ high $\leq 10^9$
