You are given a string s that consists of only digits.
Check if we can split s into two or more non-empty substrings such that the numerical values of the substrings are in descending order and the difference between numerical values of every two adjacent substrings is equal to 1.
- For example, the string
s = "0090089"can be split into["0090", "089"]with numerical values[90,89]. The values are in descending order and adjacent values differ by1, so this way is valid. - Another example, the string
s = "001"can be split into["0", "01"],["00", "1"], or["0", "0", "1"]. However all the ways are invalid because they have numerical values[0,1],[0,1], and[0,0,1]respectively, all of which are not in descending order.
Return true if it is possible to split s as described above, or false otherwise.
A substring is a contiguous sequence of characters in a string.
Example 1:
Input: s = "1234" Output: false Explanation: There is no valid way to split s.
Example 2:
Input: s = "050043" Output: true Explanation: s can be split into ["05", "004", "3"] with numerical values [5,4,3]. The values are in descending order with adjacent values differing by 1.
Example 3:
Input: s = "9080701" Output: false Explanation: There is no valid way to split s.
Example 4:
Input: s = "10009998" Output: true Explanation: s can be split into ["100", "099", "98"] with numerical values [100,99,98]. The values are in descending order with adjacent values differing by 1.
Constraints:
1 <= s.length <= 20sonly consists of digits.
