Codeforces Round #291 Div2 D

Problem
An army of n droids is lined up in one row. Each droid is described by m integers a1, a2, ..., am , where ai is the number of details of the i -th type in this droid’s mechanism. R2−D2 wants to destroy the sequence of consecutive droids of maximum length. He has m weapons, the i -th weapon can affect all the droids in the army by destroying one detail of the i -th type (if the droid doesn’t have details of this type, nothing happens to it).
A droid is considered to be destroyed when all of its details are destroyed. R2−D2 can make at most k shots. How many shots from the weapon of what type should R2−D2 make to destroy the sequence of consecutive droids of maximum length?

Solution
to - pointers 방법 으로 포인터 l = 1, r = 1 을 설정 합 니 다.t = ∑ mj = 1max (alj,..., arj) 를 구하 는데 그 중에서 aij 는 i 개인의 j 번 째 속성 을 나타 낸다.t > = k 면 r + +, 그렇지 않 으 면 l + (보증 l < = r), 이 과정 에서 r - l + 1 의 최고 치 를 계속 유지 합 니 다...
