Modular Inverse Time limit: 2 Seconds Memory Limit: 65536 KB The modular modular multiplicative inverse of an integer a modulo are an m integer x such that a-1≡x (mod m) . This was equivalent to ax≡1 (mod m) .InputThere is multiple test cases. The first line of input was an integer T ≈2000 indicating the number of test cases.Each test case contains integers 0 a ≤1000 and 0 m ≤1000.OutputFor each test case, output the smallest positive x . If such x doesn

First we need to understand how to draw arrows in SVG:Write a pair of ViewBox The area of the coordinate system reFX, Refy The datum point within the ViewBox, which is plotted at the end of the line (note case). Markerunits A datum with a size of two values: strokewidth (width of line) and Userspaceonuse (the size of the front of the graph) Markerwidth, Markerheight Size of the identity Orient D

Matplotlib can be used to create beautiful and precise mathematical graphs: However, sometimes you don't want to be so rigorous and formal when talking about ideas. You want to use a simple, graffiti-style image: The MATLAB XKCDify project can be used to generate the above graffiti: Https://github.com/slayton/matlab-xkcdify However, this article will introduce how to use the Javascript D3 library to generate your own graffiti files online, w

D3.js is a relatively strong data visualization JS tool. Use it to draw a map of China, as shown here:The source code is as follows:

)Join in some cases, List---> str# s = ' Alex ' # S11 = ' + '. Join (s) # print (S11) # L = [' Wusir ', ' Alex ', ' Taibai '] # s111 = ". Join (L) # Print (S111,type (s111))* * Repalce replaces specified charactersReplace (self, old, new, Count=none)# s = ' small matte pink ghlasdfg little Pink ' # # s12 = S.replace (' Little pink ', ' big Hammer ') # S12 = S.replace (' Little pink ', ' big Hammer ', 2) number 2 means replace only the first two characters # print (s12)Public methods' Fdsajlsk

My personal blog is: www.ourd3js.comCSDN Blog for: blog.csdn.net/lzhlzzReprint please indicate the source, thank you.The GeoJSON file was used when making a map of China. Later I found that the file was too large for 2,364 KB, and of course this ensures that the map is accurate, but we don't usually need that exact boundary, so it's necessary to narrow it down. Fortunately, there have been predecessors to do this work, really walnuts, posterity, here to express our thanks.Conversion method:1. Op
