+ * 915. Partition Array into Disjoint Intervals
+ *
+ * Given an integer array nums, partition it into two (contiguous) subarrays left and right so that:
+ * - Every element in left is less than or equal to every element in right.
+ * - left and right are non-empty.
+ * - left has the smallest possible size.
+ * Return the length of left after such a partitioning.
+ * Test cases are generated such that partitioning exists.
