Confusion in logic of leetcode problem 918
The problem is stated as following:
Given a circular integer array nums of length n, return the maximum possible sum of a non-empty subarray of nums.
A circular array means the end of the array connects to the beginning of the array. Formally, the next element of nums[i] is nums[(i + 1) mod n] and the previous element of nums[i] is nums[(i – 1 + n) mod n].
A subarray may only include each element of the fixed buffer nums at most once. Formally, for a subarray nums[i], nums[i + 1], …, nums[j], there does not exist i <= k1, k2 <= j with k1 mod n == k2 mod n.
