9156: ABC281 —— C - Circular Playlist
[Creator : ]
Description
We have a playlist with $N$ songs numbered $1, \dots, N$.
Song $i$ lasts $A_i$ seconds.
When the playlist is played, song $1$, song $2$, $\ldots$, and song $N$ play in this order. When song $N$ ends, the playlist repeats itself, starting from song $1$ again. While a song is playing, the next song does not play; when a song ends, the next song starts immediately.
At exactly $T$ seconds after the playlist starts playing, which song is playing? Also, how many seconds have passed since the start of that song?
There is no input where the playlist changes songs at exactly $T$ seconds after it starts playing.
