We know that looking for a maximum number in a data set with a capacity of N, no matter what comparison algorithm is used, it should be at least n-1 times, even if it is sorted by a competition, it will be n-1 times, otherwise, you cannot guarantee the maximum number. So what is the minimum number of comparisons between the maximum number and the minimum number in a data set with a capacity of N?The Optimal Method for Finding the maximum and minimum numbers simultaneously from a data set with a
