4 Values whose Sum is 0 https://ac.nowcoder.com/acm/problem/107382 在此处时,是将前两列的数字进行相加,然后对后两列的数字进行相加,再分别用两个数组分别记录前两列和后两列的数字的结果,对后两列的数组的结果进行单调递增的排序,然后对后两列的数组采用lower_bound和upper_bound去寻找前两列数组的相反...

4 Values whose Sum is 0 Description The SUM problem can be formulated as follows: given four lists A, B, C, D of integer values, compute how many quadruplet (a, b, c, d ) ∈ A x B x C x D are such that a + b + c + d = 0 . In the following, we assume that all l...
4 Values whose Sum is 0 (二分) 思路:分治法 枚举4组数O(n^4)绝对超时 因此可以使用分治的思想,将 4 组数分为两组,然后每组再分别计算和,最后对两组合进行排序,让正数与负数相加判断是否为 0 即可 1#include <iostream>2#include <cstring>3#include <cstdio>4#include <algorithm>56usingnamespacestd;...
4 Values whose Sum is 0 4 Values whose Sum is 0 如果直接暴力枚举的话,其复杂度为O(n4)O(n4),这是必然超时的。 但是如果把这四个序列分成两半,通过遍历一半,而到另外一半去进行二分查找的话,复杂度就可以降为O(n2log(n))O(n2log(n))。

The first line of the input file contains the size of the lists n (this value can be as large as 4000). We then have n lines containing four integer values (with absolute value as large as 228 ) that belong respectively to A, B, C and D . ...
The values are driven by the (G)MCH between PWROK assertion and FSB_CPURSTINB deassertion to allow processor configuration. I/O GTL+ 2x Host Address Strobe: The source synchronous strobes used to transfer FSB_AB_[31:3] and FSB_REQB_[4:0] at the 2x transfer rate. Strobe Address Bits...

The preceding methods are still called, but their return values are discarded. In most scenarios in which multicast delegates are used, they have void return types, so this subtlety does not arise. 提示 All delegate types implicitly inherit System.MulticastDelegate, which inherits from System....
