obviously cannot form a text string...Then I want to find that the short string does not need to overlap and overwrite the long string. Then I started to write the program, and then wa again. Then I found that AA and AAA can form the echo string...In desperation, I consulted vfleaking and found this algorithm:Lexicographic hash.We first insert all strings into a trie tree, then calculate the hash of each string, and then enumerate each string, go down along the trie tree, and enumerate each pre

General question:
First of all, the "general question" described below is not the original intention of the question, but it is impossible to perform AC based on the original intention of the question, because the test database is very different from the original intention of the question. By the way, it is recommended that you do not want to do this if you are new to poj, because if you do

of standards from different origins: CIF, Sif, and D1.
I. CIF
The common intermediate format (common media format), also known as fcif (full CIF), is a standard format used to regulate the pixel resolution of video signals of The YCbCr chromatic aberration component, it is often used in Video Conferencing Systems in the telecom field.
The CIF format is the H.261 video encoding standard (ITU-T H.261) launched by the International Telecommunication Union (ITU) in 1990) the first defined format st
using D and K system). In the era of color television, the format has been simplified into three types: NTSC, PAL, SECAM, where NTSC is divided into NTSC4.43 and NTSC3.58. China's color TV is used in the PAL system D modulation mode, so also called pal-d format. Interested can be Baidu encyclopedia "TV format" to learn more about.In addition, you may find that t
. dat files in the VCD CD.MPEG1: Technical Features: MPEG-1 developed in 1992, can be applied to different bandwidth devices, such as CD-ROM, VIDEO-CD, cd-i. Its purpose is to compress the NTSC image of 221MBIT/S to 1.2mbit/s with a compression rate of 200:1. This is the industry recognition standard for image compression. It can be for the SIF standard resolution (for NTSC system 352x240; for PAL system 352x288) image compression, transfer rate of 1.
V4L is the acronym for Linux, which is the subsystem of the Linux kernel about video devices, it provides a unified interface for the video drive under Linux, allowing applications to operate different video devices using a unified API function, which greatly simplifies the development and maintenance of video systems. Since the early v4l had a lot of flaws, Bill Dirks and others redesigned it and named video-for Linux 2 (V4L2), which was first seen i
acronymsAcronyms are words that consist of the first letter of each word in a term or phrase. For example, HTML is an acronym for Hypertext Markup Language. Acronyms should be used in identifiers only if they are widely recognized and understood by the public. Acronyms are different from abbreviations because abbreviations are abbreviations for a word. For example, theID is an abbreviation for identifier . Typically, the library name should not use a
