Faster Input Scan Method in C
Sometimes we need to scan input really fast like when we are participating in coding competitions like codechef or SPOJ where the time limit is very strict and inputs are large, we can save some time by adopting faster scanning methods. We can achieve our gaol using getchar_unlocked function. code below scans 100000 integers and has two different methods one is scan_normal() this will scan integers using standard scanf() function and the other one is scan_fast() this scan integers using getchar_unlocked function, we will execute the program twice one for each method mark the time taken for execution to evaluate the performance....
