SPOJ POSTERS TLE (Segment tree).
Difference between en1 and en2, changed 437 character(s)
I am getting TLE in this problem. I used lazy propagation with co-ordinate compression.↵

How do I apply co-ordinate compression here ?↵

If points (1,4), (2,6), (8,10), (3,4), (7,10). If I sort it and stored the indices in hashmap, then (1,2,3,4,6,7,8,10) will be compressed to (1,2,3,4,5,6,7,8).If I compress it this way then it fails for this test case.↵

I get answer as 4 because poster 3 at point (5,5) is not stored here as we have no index for 5.↵

I am newbie to this topic.↵
Any help would be appreciated.
