MULTQ3  Multiples of 3
There are N numbers a[0],a[1]..a[N  1].
Initally all are 0. You have to perform two types of operations :
1) Increase the numbers between indices A and B (inclusive) by 1.
This is represented by the command "0 A B"
2) Answer how many numbers between indices A and B (inclusive) are divisible by 3.
This is represented by the command "1 A B".
Input
The first line contains two integers, N and Q. Each of the next Q lines are either of the form "0 A B" or "1 A B" as mentioned above.
Output
Output 1 line for each of the queries of the form "1 A B" containing the required answer for the corresponding query.
Sample
Sample Input : 4 7 1 0 3 0 1 2 0 1 3 1 0 0 0 0 3 1 3 3 1 0 3 Sample Output : 4 1 0 2
Constraints
1 <= N <= 100000
1 <= Q <= 100000
0 <= A <= B <= N  1

Why do setters keep such time limits which give AC or TLE on the basis of fast IO? If NlogN is expected complexity, then poorer algos (N^2 etc) will timeout even if they make the limit a little less stringent.

Tle in java, used fast i/o, any other way to resolve it?

no need prinf and I make three mod =))

2D array does the trick :)

Good one....segment trees+lazy propagation!!:)

Can it be solved without using lazy propagation?

Time limit of JAVA is not correct. Same code running in cpp with scanf and printf

AC in 1 go! Nice Problem! :D
