Given a positive integer num
, split it into two non-negative integers num1
and num2
such that:
num1
and num2
is a permutation of num
.\n\n\tnum1
and num2
is equal to the number of occurrences of that digit in num
.num1
and num2
can contain leading zeros.Return the minimum possible sum of num1
and num2
.
Notes:
\n\nnum
does not contain any leading zeros.num1
and num2
may differ from the order of occurrence of num
.\n
Example 1:
\n\n\nInput: num = 4325\nOutput: 59\nExplanation: We can split 4325 so that\n\nnum1
is 24 and num2is
35, giving a sum of 59. We can prove that 59 is indeed the minimal possible sum.\n
Example 2:
\n\n\nInput: num = 687\nOutput: 75\nExplanation: We can split 687 so that\n\nnum1
is 68 andnum2
is 7, which would give an optimal sum of 75.\n
\n
Constraints:
\n\n10 <= num <= 109
给你一个正整数 num
,请你将它分割成两个非负整数 num1
和 num2
,满足:
num1
和 num2
直接连起来,得到 num
各数位的一个排列。\n\n\tnum1
和 num2
中所有数字出现的次数之和等于 num
中所有数字出现的次数。num1
和 num2
可以包含前导 0 。请你返回 num1
和 num2
可以得到的和的 最小 值。
注意:
\n\nnum
保证没有前导 0 。num1
和 num2
中数位顺序可以与 num
中数位顺序不同。\n\n
示例 1:
\n\n\n输入:num = 4325\n输出:59\n解释:我们可以将 4325 分割成\n\nnum1
= 24 和num2
= 35 ,和为 59 ,59 是最小和。\n
示例 2:
\n\n\n输入:num = 687\n输出:75\n解释:我们可以将 687 分割成\n\nnum1
= 68 和num2
= 7 ,和为最优值 75 。\n
\n\n
提示:
\n\n10 <= num <= 109
