## Problem 2: This Message will Self-Destruct

Ethan Hunt has received an audio message recorded by Alan Hunley, the secretary of the IMF, detailing a secret upcoming mission to Newfoundland. Ethan is well aware of a security protocol dictating that the message must self-destruct shortly after being heard, in order to prevent its information from falling into enemy hands. Normally, Alan would end the message by mentioning how quickly it will self-destruct, but it appears that he forgot to do so this time!

Fortunately, the message did come with a digital clock display instead, which is ticking downwards. Ethan assumes that the message will self-destruct when the clock reaches 0:00.

The current clock display may be represented by a string S with exactly four characters, in the format "`m:ss`". The first character ("`m`") is a digit "`0`".."`9`", and indicates the number of minutes remaining. The second character is always "`:`". The last two characters ("`ss`") form a number ("`00`".."`59`"), indicating the number of seconds additionally remaining. Specifically, the third character is a digit "`0`".."`5`", while the fourth character is a digit "`0`".."`9`". It's guaranteed that S is not already equal to "`0:00`".

Based on the clock display, help Ethan determine how many seconds he has left to get the message off his hands before it self-destructs!

### Input Format

The first and only line of input consists of a single string, S (having exactly 4 characters, in the format "`m:ss`").

### Output Format

Output a single integer, the number of seconds remaining until the message self-destructs.

```2:07
```

```127
```

### Sample Explanation

The message will self-destruct in 2 minutes and 7 seconds, which is equivalent to 127 seconds.
