Q4. Static Code Analysis — C

The original problem gives a C function that returns 0 for an odd input and 1 for an even input, and calls it twice in a row starting from i=3. This site keeps the function and the number of calls, but reads the initial i from input and outputs the value after the second call.

输入格式

One line with one signed 32-bit integer i.

输出格式

Output the integer result after calling the original function twice in a row.
