Suppose I have a map in Java which looks like this:
{
39:"39 to 41",
41:"41 to 43",
43:"43 to 45",
45:">=45"
}
If the keys are in sorted order(either using treemap or linkedhashmap).Now if i try to get a value which is >=39 and <41.Then I should get the String "39 to 41".How do I do this efficiently?
