You are given a positive integer num
consisting of exactly four digits. Split num
into two new integers new1
and new2
by using the digits found in num
. Leading zeros are allowed in new1
and new2
, and all the digits found in num
must be used.
num = 2932
, you have the following digits: two 2
's, one 9
and one 3
. Some of the possible pairs [new1, new2]
are [22, 93]
, [23, 92]
, [223, 9]
and [2, 329]
.Return the minimum possible sum of new1
and new2
.
\n
Example 1:
\n\n\nInput: num = 2932\nOutput: 52\nExplanation: Some possible pairs [new1, new2] are [29, 23], [223, 9], etc.\nThe minimum sum can be obtained by the pair [29, 23]: 29 + 23 = 52.\n\n\n
Example 2:
\n\n\nInput: num = 4009\nOutput: 13\nExplanation: Some possible pairs [new1, new2] are [0, 49], [490, 0], etc. \nThe minimum sum can be obtained by the pair [4, 9]: 4 + 9 = 13.\n\n\n
\n
Constraints:
\n\n1000 <= num <= 9999
给你一个四位 正 整数 num
。请你使用 num
中的 数位 ,将 num
拆成两个新的整数 new1
和 new2
。new1
和 new2
中可以有 前导 0 ,且 num
中 所有 数位都必须使用。
num = 2932
,你拥有的数位包括:两个 2
,一个 9
和一个 3
。一些可能的 [new1, new2]
数对为 [22, 93]
,[23, 92]
,[223, 9]
和 [2, 329]
。请你返回可以得到的 new1
和 new2
的 最小 和。

示例 1:
\n\n输入:num = 2932\n输出:52\n解释:可行的 [new1, new2] 数对为 [29, 23] ,[223, 9] 等等。\n最小和为数对 [29, 23] 的和:29 + 23 = 52 。\n\n\n
示例 2:
\n\n输入:num = 4009\n输出:13\n解释:可行的 [new1, new2] 数对为 [0, 49] ,[490, 0] 等等。\n最小和为数对 [4, 9] 的和:4 + 9 = 13 。\n\n\n
