You are given a string s consisting of digits from 1 to 9 and an integer k.

\n\n

A partition of a string s is called good if:

\n\n\n\n

Return the minimum number of substrings in a good partition of s. If no good partition of s exists, return -1.

\n\n

Note that:

Example 1:

\n\n
\nInput: s = "165462", k = 60\nOutput: 4\nExplanation: We can partition the string into substrings "16", "54", "6", and "2". Each substring has a value less than or equal to k = 60.\nIt can be shown that we cannot partition the string into less than 4 substrings.\n
\n\n

Example 2:

\n\n
\nInput: s = "238182", k = 5\nOutput: -1\nExplanation: There is no good partition for this string.\n
