Hello,

One thing I like about AtCoder is the post contest videos. For example: https://www.youtube.com/watch?v=nXyz3oUEidc.
Unfortunately they are in Japanese. I think they would have more impact if they were in English.
What do you think?

Does anyone has a proof of the formula for problem C, the time T that the two flames meet is expressed as follows:

$$$ T = \frac{1}{2} \sum_{i=1}^{N} \frac{A_i}{B_i} $$$

Thanks
