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 <= 105nconsists of only digits.ndoes not contain any leading zeros and represents a positive integer.
Solution
public class Solution {
public int minPartitions(String n) {
char[] tempArray = n.toCharArray();
int result = 0;
for (int i = 0; i < n.length(); i++) {
result = Math.max(result, tempArray[i] - 48);
}
return result;
}
}
