problem statement says

For each testcase, print the number of ways Jim can buy candies from the shop in a newline. If the answer has more than 9 digits, print the last 9 digits.

which is incorrect, since it does not expect you to print leading zeros. instead of slicing the string simply do mod 1e10

In C# I am logging the answer which is the same as the expected answer but still getting the wrong answer. Per somebody's suggestion about C I tried adding a logger right before I return to no avail. I tried adding a logger to the solution code right after the return to no avail. In both cases it logs the expected answer but still getting the wrong answer. What gives?!?

In some languages this does not submit correctly.

In Node.js, paste:

ws.write(result + "\n")

at the end of function main's for loop.

Cheers!

The Python template is missing the code to write the result to stdout. You can add the following lines to do so:

        fptr.write(str(result))
        fptr.write('\n')

This code efficiently calculates the number of ways Jim can buy candies, a common problem in computer science courses. I am getting assignment help from it.
