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
