Given a positive-integer array where you may replace any contiguous subarray by its sum, find the maximum number of contiguous segments you can partition the array into so that the sequence of segment sums is non-decreasing. With n up to 1e5, this reduces to greedily merging adjacent elements/segments until the sequence of segment sums becomes non-decreasing.
