Use segment tree and compression

Process it offlyn,so that u know what values are going to be there ,map values to small values

Now create a segment tree which stores no.of elements in a range ,so each time if +1,add to segment,if -1,we know how many elements we have so query the segment tree for the n/2th element assumning we have n elements upto now(we can easily calculate xth element-if left child value>=x ,xth element lies in left part,else in right part)

We can delete the median after that
