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
