1689. Partitioning Into Minimum Number Of Deci-Binary Numbers

Medium

---

A decimal number is called deci-binary if each of its digits is either 0 or 1 without any leading zeros. For example, 101 and 1100 are deci-binary, while 112 and 3001 are not.

Given a string n that represents a positive decimal integer, return the minimum number of positive deci-binary numbers needed so that they sum up to n.

Example 1:

Input: n = "32"
Output: 3
Explanation: 10 + 11 + 11 = 32

Example 2:

Input: n = "82734"
Output: 8

Example 3:

Input: n = "27346209830709182346"
Output: 9

Constraints:

• 1 <= n.length <= 105

• n consists of only digits.

• n does not contain any leading zeros and represents a positive integer.

class Solution:
    def minPartitions(self, n: str) -> int:
        maximum = 0
        for char in list(n):
            maximum = max(maximum, int(char))
        return maximum
