Guess the number

AekdyCoin is the most powerful boy in the group ACM_DIY, whose signature is valuable. In order to get his signature, you must first solve this problem. But don't be worried, because this is the easiest problem in the world. You are given only one sentence written in English. You are asked to output a single integer implied by this sentence.

There is only one line in the input. It is a sentence which implies some integer. The length of the sentence is no more than 16. The sentence contains only letters(both uppercase and lowercase), digits, and whitespace. You may assume the given sentence is written in standard English, and always implies exactly one single integer.

There is only one integer to output: that is the integer implied by the input sentence. You may assume this integer is in the range of 32-bit signed int.
