Given two lists of **closed** intervals, each list of intervals is pairwise disjoint and in sorted order.

Return the intersection of these two interval lists.

*(Formally, a closed interval **[a, b]** (with **a <= b**) denotes the set of real numbers **x** with **a <= x <= b**. The intersection of two closed intervals is a set of real numbers that is either empty, or can be represented as a closed interval. For example, the intersection of [1, 3] and [2, 4] is [2, 3].)*
