Fgets vs scanf

[rajdeepgupta]

Hello, I was trying to learn some fast I/O. I solved the problem Blubberies(http://www.spoj.pl/status/RPLB,rajdeepgupta20/) using scanf and it took 0.80s. And then I used fgets and strtol to read the input. I was expecting to get a better runtime . But it took 0.84s. Is fgets slower than scanf?? Please suggest me some way to improve the runtime. Thanks in advance.
Note: I used printf to output the result in both cases.

I wouldn't think that fgets would be any faster than scanf for this problem. You're only reading one line at a time with fgets, and in this problem there are at most two numbers per line. For a faster input method you could look at using read or the other functions like it. The reason this will be faster is that it reduces the number of read operations.
