2-D segment tree with less memory
Hi,
I am trying to implement a 2-D segment tree, seg with N = 100000... The catch is that I only need to get the query answer for Q(100000) nodes say query(i,j) : denoting the value in seg[i][j]... but i need to online (lazily) update the seg tree, seg[lx...rx][ly...ry].
Can anyone help me with this problem?
