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.
\n
Example 1:
\n\n\nInput: n = "32"\nOutput: 3\nExplanation: 10 + 11 + 11 = 32\n\n\n
Example 2:
\n\n\nInput: n = "82734"\nOutput: 8\n\n\n
Example 3:
\n\n\nInput: n = "27346209830709182346"\nOutput: 9\n\n\n
\n
Constraints:
\n\n1 <= n.length <= 105n consists of only digits.n does not contain any leading zeros and represents a positive integer.如果一个十进制数字不含任何前导零，且每一位上的数字不是 0 就是 1 ，那么该数字就是一个 十-二进制数 。例如，101 和 1100 都是 十-二进制数，而 112 和 3001 不是。
给你一个表示十进制整数的字符串 n ，返回和为 n 的 十-二进制数 的最少数目。

示例 1：
\n\n输入：n = \"32\"\n输出：3\n解释：10 + 11 + 11 = 32\n\n\n
示例 2：
\n\n输入：n = \"82734\"\n输出：8\n\n\n
示例 3：
\n\n输入：n = \"27346209830709182346\"\n输出：9\n\n\n

提示：
\n\n1 <= n.length <= 105n 仅由数字组成n 不含任何前导零并总是表示正整数\\u7248\\u672c\\uff1a \\u7f16\\u8bd1\\u65f6\\uff0c\\u5c06\\u4f1a\\u91c7\\u7528
