# Exercise 14.3.2

Rewrite the code for INTERVAL-SEARCH so that it works properly when all intervals are open.

This is pretty minor, and I'm not gonna bother doing the full thing. We need to do to things to the code in Exercise 14.3-1:

• change the definition of overlaps to exclude the boundary conditions, that is, change <= to < in the comparisons;
• use > instead of >= when comparing node.left.max and interval.low in Tree.search.
