For some weird reason my code runs faster with linear search compared to binary search.
sort - binary search 0.156s
sort - linear search 0.144s
linear search 0.152s

My experience:
when you catenate the strings you have to remember to add the '\n'

Well, I think the best way to read input is to find ".," and ".:" instead of "," and ":" .
I am also sure that there is no extra blank spaces in each line of input. (Mine got AC)
