#### I have started to solve some Segment Tree problems recently and I had some queries about the Lazy Propagation Technique.↵
↵
I understand the basic concept of Lazy Propagation and have solved some problems (all of them in the format : **Add** v to each element in the range [i,j] , Answer the sum , maximum/minimum element ,some info for elements in range [a,b]).↵
↵
↵
I got the concept for the **add**ing element Lazy Propagation . But I have some confusion about **changing** the elements to v for all elements in the range [i,j] problem .↵
↵
↵
My question is , what is the general concept that I should have in mind while finding solution for these and more harder variations?↵
I have seen lots of code online but they are mostly for the first version of the problem which I think I understand but I just don't know how to apply this concept to solve other variation of Lazy propagation problem.↵
↵
And I also need some tips on debugging Segment tree problems.Thanks
