An I/O problem about 767D

Revision en1, by lkmcfj, 2017-02-20 05:55:36

My code got TLE9(n=m=1e6,k=2e6) on 767D - Cartons of milk.24775880 the complexity is O(n+m) In custom test,when I replaced the input part with random(the input file was too large),the program took 1763ms.When I deleted the output part,it turned out to be 31ms.Most of the time is spent on I/O. So is there any trick to make I/O faster in pascal(just like what we use in c++),or this problem is impossible to solve in pascal? //sorry for my poor English
