Of course, as n is very large(10^6) the good approach is to use segment tree to store intervals, and also to use lazy propagation to update the tree in log n. But I actually really don't know how to apply lazy propagation here, because you have to keep into account three possible ...
I am learning segment tree with lazy propagation but i can't find good tutorial. Can anyone post a code that implements this two operation with segment tree and lazy propagation: a-add a value to every element in a interval b-get the. sum of interval. Thanks in advance....
I'm learning segment tree data structure and I've learned the (Build, update, query) functions,and I'm trying to make an update on an interval using lazy propagation algorithm but I can't find the correct implementation of it. Would you please provide me with the correct code of lazy p...
seg_tree_lazy<node,update>st(N,{0,0},{false,0}); Then, we set the leaf values: vector<node>leaves(N,{0,1});st.set_leaves(leaves); And we're done! With this example we can see the power of modularization; the amount of code we had to touch is very small. You can see the...
