n is the number of tasks (numbered from 1 to n ) and m is the number of direct precedence relations between tasks. 2018-2019 ICPC, Northern Eurasia, Southern Subregional Contest [Mirror] Saratov State U, Codeforces, October 19, 2018 Input The first line of the input contains single integer n (1 n 2 105) — total number of IPv4 subnets in the input. The contests conducted by Codeforces allow you to write solutions to the problems that are tested during the contest. Those who pass that set of solution tests receive the opportunity to go through the sources of other contestants, search for mistakes there and suggest the tests on which these solutions do not work. such disordered form, the method can do nothing.[? If you want to get the most benefit out of the practice problem, you should keep working on it as long as you're still making progress.

In the first line there is an integer N (N = 100000) Each query is represented by two numbers L and R, and it asks you to compute some function Func with subarray Arr[L..R] as its argument.. For the sake of brevity we will denote Func([L, R]) as the value of Func on subarray Arr[L..R]. Each instance begins with a line containing two integers, 1<= n<= 100 and m . Edit sessions The input will consist of several instances of the problem. TheKnights ACM-ICPC Amritapuri onsite regionals 2012. Problem F.
