You are given an integer array nums.
You replace each element in nums with the sum of its digits.
Return the minimum element in nums after all replacements.
Example 1:
Input: nums = [10,12,13,14]
Output: 1
Explanation:
nums becomes [1, 3, 4, 5] after all replacements, with minimum element 1.
Example 2:
Input: nums = [1,2,3,4]
Output: 1
Explanation:
nums becomes [1, 2, 3, 4] after all replacements, with minimum element 1.
Example 3:
Input: nums = [999,19,199]
Output: 10
Explanation:
nums becomes [27, 10, 19] after all replacements, with minimum element 10.
Constraints:
1 <= nums.length <= 1001 <= nums[i] <= 104[10,12,13,14] [1,2,3,4] [999,19,199]
