本周选择的算法题是:Partitioning Into Minimum Number Of Deci-Binary Numbers。
规则
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.
Solution
class Solution:
def minPartitions(self, n: str) -> int:
return int(max(n))
