The project consists of four processes: \\(A\\), \\(B\\), \\(C\\), and \\(D\\), which require \\(2\\), \\(5\\), \\(x\\), and \\(4\\) days to complete, respectively. The sequence and relationship of the four processes are as follows: \\(A\\) and \\(B\\) can start at the same time; after completing \\(A\\), \\(C\\) can start; after completing \\(B\\) and \\(C\\), \\(D\\) can start. If the total duration of the project is \\(9\\) days, the maximum number of days required to complete process \\(C\\) is \_\_\_\_\_\_.
