Hours, Minutes, Seconds -> Seconds

Convert given hours, minutes, and seconds into total seconds.

Example

If 1 hour, 2 minutes, and 3 seconds are given, the total seconds are:

1 × 3600 + 2 × 60 + 3 = 3723 seconds.

Three integers — hours, minutes, and seconds — separated by spaces, given in a single line.

Output the total number of seconds.

• 0 ≤ hours ≤ 10⁶
• 0 ≤ minutes ≤ 59
• 0 ≤ seconds ≤ 59
