Glad you're back!!!

In short, it makes cin/cout faster.

@@Errichto Is it actually any better than using scanf() and printf()? I've done some testing myself and found that cin/cout with the boost are faster but I've also found conflicting results on the internet. What's your experience with the two approaches

In the last problem can we just put a if statement that adds x if i is in range l to r please correct me if i am wrong And also as some one who just cp is a2oj a good resource or should i do something else also

If you do it separately for each of Q updates, the total time complexity is O(N*Q), which is too slow. a2oj is ok as long as you solve problems that are difficult enough for you.

Hi from Banja Luka

It's been a while 😭

Can you make a tutorial on problem solving. Like picking a harder problem and showing how to come up with some initial observations and ideas and work trough them to come up with a solution. A lot of times I just end up with a blank screen having difficulty even understanding what the problem is about.

I have hundreds of videos & streams about problem solving across my two channels. I rarely solve anything without explaining the thought process. If you want to see me struggle for hours, see any Atcoder Grand Contest streams like this one kzread.info/dash/bejne/h36m3Mmjks-zc7A.html

first problem is basically what integral images are about.

why dont we just go through the range form a to b and up the elements instead of summing from 0 to b then from 0 to a and taking the prior minus the latter?
