| Video Length in Seconds |
You are given the length of a video in minutes. The format is mm:ss (ex: "02:54"). |
| Create a function that takes the video length and return it in seconds. |
| Examples |
<br>minutesToSeconds("01:00") = 60<br><br>minutesToSeconds("13:56") = 836<br><br>minutesToSeconds("10:60") = -1<br><br>minuteToSeconds("121:49") = 7309<br> |
| Notes |
- The video length is given as a string.
- If the number of seconds is 60 or over, return -1 (see example #3).
- You may get a number of minutes over 99 (e.g. "121:49" is perfectly valid). |
