Thinking about it: When I saw this problem, I immediately thought of the HDU 1496, the two topics have similarities. My personal hdu1496: Click hereSave all the first and second numbers and A + B, record the number of occurrences of each number, and then calculate each C + D, for each C + D, the query-(c + D) appears several times.So the subject needs a way to save all A + B's and its occurrences.The most straightforward approach is to use the map in the STL, but the map is easy to time out when

The meaning of the topic is very clear, ABCD four sets, extracting a number from each set, and adding four numbers equals 0 of the combined number.Because n maximum reaches 4000, so, the method of violence can not live, is the time limit is 15000MS also not.But we can search two-way, that is binary search.First find the CD of the two sets of 22 pairs of new collection CD, and then in the collection from the CD to look for AB set 22 paired and K negati

DescriptionThe 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) ε a x B x C x D are such that A + B + C + D = 0. in the following, we assume that all lists have the same size N. InputThe 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 2

two hundred 16 bit SDRAM, then the same is different, that is to say,We can merge the two SDRAM databases into a 32-bit SDRAM, so that the 32-Bit Memory input requires one CLK !! 32-bit data should be written into the SDRAM in one CLK, using the concurrency of the hardware,We can have two masters. At the same time, we can import 16 low-bit 32-bit data into 1st slave SDRAM, and 16 high-bit data into 2nd slave SDRAM.. However, there are two methods:1. Change the data bus of the master IP addre
