2578 - Split With Minimum Sum.

Easy

Given a positive integer num, split it into two non-negative integers num1 and num2 such that:

  • The concatenation of num1 and num2 is a permutation of num.
    • In other words, the sum of the number of occurrences of each digit in num1 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:

  • It is guaranteed that num does not contain any leading zeros.
  • The order of occurrence of the digits in num1 and num2 may differ from the order of occurrence of num.

Example 1:

Input: num = 4325

Output: 59

Explanation: We can split 4325 so that num1 is 24 and num2 is 35, giving a sum of 59. We can prove that 59 is indeed the minimal possible sum.

Example 2:

Input: num = 687

Output: 75

Explanation: We can split 687 so that num1 is 68 and num2 is 7, which would give an optimal sum of 75.

Constraints:

  • 10 <= num <= 109
