Maximum Number of Groups Getting Fresh Donuts, LeetCode 1817. In this situation, however, we only need to perform the first part of the bucket sort. And since we only need to make one comparison per pair of buckets with consecutive numbers, and as there are only a maximum of 2 * N buckets, the comparisons will only take O(N) time, as well. If we make sure to define the bucket size smaller than this value, then as stated earlier, the two numbers that form the maximum gap will have to be found in separate buckets. For example, if 53 is pushed twice, the first copy will be saved to Stack 1, the second copy to Stack 2.
