1849 - Splitting a String Into Descending Consecutive Values.
Medium
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.
s = "0090089" can be split into ["0090", "089"] with numerical values [90,89]. The values are in descending order and adjacent values differ by 1, so this way is valid.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.
