SP3973 M00PAIR - 0 0 Pairs

Description

[English](/problems/M00PAIR/en/) [Vietnamese](/problems/M00PAIR/vn/)A sequence consisting of one digit, the number 1 is initially written into a computer. At each successive time step, the computer simultaneously tranforms each digit 0 into the sequence 1 0 and each digit 1 into the sequence 0 1. So, after the first time step, the sequence 0 1 is obtained; after the second, the sequence 1 0 0 1, after the third, the sequence 0 1 1 0 1 0 0 1 and so on. How many pairs of consequitive zeroes will appear in the sequence after n steps? ### Input Clarification for this Problem: The Range of inputs is from 1 to 999 in some order and in particular not in ascending order ### Output For each input n print the number of consequitive zeroes pairs that will appear in the sequence after n steps. ### Sample ``` Sample Input 1 2 3 4 5 Sample output 0 1 1 3 5 ``` **Notice : Long output - 1.45MB** - there are a lot of input/output so it is easy to TLE if you dont optimize in/out if you use Java ...
