**Credit to ** for tweaking the problem to be harder.

is having trouble with his Latin homework. Since he wants to study for his summatives, he has translated the problem and entrusted you with this task instead.

He has given you segments. Segment covers the interval and has a value . We say that segment *covers* segment if every point in is inside segment , and this would still hold true if segment were shifted to the left or to the right by . These segments are special - if two segments share a point, then the larger segment covers the smaller segment.

He gives you queries in the form of `a b`

. For each query, find the ID of the segment with lowest value that covers both segments and . If there are no such segments, output `-1`

.

If there is more than one segment that covers and of the same value, output the one of smallest length.

Please help

Are the segments distinct?

`In other words, there cannot be any two segments that partially share a range (this includes the ends).`
