![3. Let X be a set of n intervals on the real line. We say that a subset of intervals
Y CX covers X if the union of all intervals in Y is equal to the union of all
intervals in X. The size of a cover is just the number of intervals.
Describe and analyze an efficient algorithm to compute the smallest
cover of X. Assume that your input consists of two arrays L[1..n] and
R[1..n], representing the left and right endpoints of the intervals in X. If
you use a greedy algorithm, you must prove that it is correct.
