Intersection X96828

Statement

Let $a, b, c, d$ be integers such that $a\le b$ and $c\le d$ . Write a function @intersection(a, b, c, d)@ that assuming that intersection of intervals $[a, b]$ and $[c, d]$ is non empty returns the tuple of integers $(p, q)$ such that $[p, q] = [a, b] \cap [c, d]$ .

Sample session

>>> intersection(1, 5, 3, 7)
(3, 5)
>>> intersection(10, 16, 12, 15)
(12, 15)
>>> intersection(3, 5, 2, 11)
(3, 5)
>>> intersection(1, 4, 4, 6)
(4, 4)
