I need a solution for following computing problem for millions of ids. I have list of followings ids (sample)

SEQ1 225 275
SEQ1 200 300
SEQ1 201 299
SEQ1 250 399
SEQ1 145 244
SEQ2 120 130
SEQ2 100 150
SEQ2 101 149
SEQ2 120 230
SEQ2 99 140

I want to remove/discard those ids-range which completely fall within others range, and keep the rest.

In other word, it should print the following ids

SEQ1 200 300
SEQ1 250 399
SEQ1 145 244
SEQ2 100 150
SEQ2 120 230
SEQ2 99 140

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
