+ * 1431. Kids With the Greatest Number of Candies
+ *
+ * There are n kids with candies. You are given an integer array candies, where each candies[i] represents the number of candies the ith kid has, and an integer extraCandies, denoting the number of extra candies that you have.
+ * Return a boolean array result of length n, where result[i] is true if, after giving the ith kid all the extraCandies, they will have the greatest number of candies among all the kids, or false otherwise.
+ * Note that multiple kids can have the greatest number of candies.
