Discussion thread.

We can solve a question like "counting the numbers between range which follow some properties" using Digit DP, like count the n digit number whose sum of digits is divisible by 3.

But how can we solve, "sum of the numbers between range which follow some properties" like "sum of n digit numbers whose digit sum is divisible by k". constraints: n = 1e5, 2 <= k <= 10

Please give me a link where I can read about how to solve these types of problems.

A Python Script which will be responsible for notifying announcement of the running contest on Codechef. (Here is the link of file).

One day due to not aware of no alert message of the announcement in the ongoing contest, I could not solve a problem. That's why I decided to do this.

Tell me If there is any problem to use this. This will work on every OS. Then use it in the upcoming contest.
