Let's denote the median of a sequence s with odd length as the value in the middle of s if we sort s in non-decreasing order. For example, let s = [1, 2, 5, 7, 2, 3, 12]. After sorting, we get sequence [1, 2, 2, \underline{3}, 5, 7, 12], and the median is equal to 3. You have a sequence of n integers [1, 2, ..., n] an...
