To execute any linux command in background we use nohup. But the problem with scp command is that it prompts for the password (if password authentication is used). So to make scp execute as a background process do this:


1>
$ nohup scp file_to_copy user@server:/path/to/copy/the/file > nohup.out 2>&1
if it prompts for password then enter password.
Then press ctrl + z which will temporarily suspend the command, 


SCP will give output:

/*
A zero-indexed array A consisting of N different integers is given. The array contains integers in the range [1..(N + 1)], which means that exactly one element is missing.

Your goal is to find that missing element.

Write a function:

    int solution(int A[], int N); 

that, given a zero-indexed array A, returns the value of the missing element.
