/**
 * 1085. Sum of Digits in the Minimum Number
 *
 * Given an array A of positive integers, let S be the sum of the digits of the minimal element of A.
 * Return 0 if S is odd, otherwise return 1.
 *
 * Example 1:
 * Input: [34,23,1,24,75,33,54,8]
 * Output: 0
 * Explanation:
 * The minimal element is 1, and the sum of those digits is S = 1 which is odd, so the answer is 0.
 *
 * Example 2:
 * Input: [99,77,33,66,55]
 * Output: 1
 * Explanation:
 * The minimal element is 33, and the sum of those digits is S = 3 + 3 = 6 which is even, so the answer is 1.
 *
 * Note:
 * 1 <= A.length <= 100
 * 1 <= A[i].length <= 100
