Episode 4-Play complete song after clicking on PREV

[kanch21]

Scenario- Play a song for X minutes, click on previous and let the same song play completely.

Note- Click on PREV means you are wanting to play the same song from start.

Flow of scenario- Play a song for X min-> Click on PREV-> Let the same song be played completely.

Issue-

1. The listening time gets computed upto (Play a song for X min-> Click on PREV). But it does not compute for (Click on PREV-> Let the same song be played completely.)

Note- There is no record for the song in the file if its played completely as the next record is the next song whatsoever. So we need to check how this can be incorporated.

Input Snippet-

The Python code needs to be implemented.
Tip- We can build a logic to compute the listening time between PREV(idx-1)of song 1 and PLAY(idx) of song 2
