1000001
Your code’s output will be 925001
Correct answer is 925000
And if you want AC
Change this line from your code : s=s+(n-1500000)*3/10;
and modify it to : s=s+(n-1500000)*0.3;
And you are ready to go

here’s a solution and an idea to minimise the number of brackets as it makes it harder to debug and much difficult to find where it went wrong 
There’s where i got confused , The Brackets

Try taking input as double. If you keep your answer in long or integer datatype for sum, while computing ( e.g. s=s+(n-1000000)*0.2 ), you will definitely incur some loss in some cases.
