问题 how to calculate (A*B*C)%10000007 where A,B,C can be maximum 10^18 回答1: Let I = 10000007, so A = n1 * I + X1 B = n2 * I + X2 C = n3 * I + X3 A * B => (n1 * I + X1) (n2 * I + X2) => n1 * n2 * I^2 + n1 * X2 * I + n2 * X1 * I + X1 * X2 Only X1 * X2 can't div by I Hence, A * B % I === X1 * X2 % I === (A % I) * (B % I) % I Therefore (A * B * C) % I === [(A % I) * (B % I) % I] * (C % I) % I 来源： https://stackoverflow.com/questions/14189713/how-to-calculate-abc10000007-where-a-b-c-can-be-at-maximum

问题 I'm new to jQuery and stack overflow, so I'll try to be specific, but please bear with me. I'm trying to create a text slider with associated links from scratch, using modulus to iterate through the list and repeat. Here's the code I'm working with: ul#text { position: relative; margin-bottom: 40px; height: 40px; } ul#text li { position: absolute; display: none; } .active { font-weight: bold; } <ul id="text"> <li id="textBody">Suffering is not a result of physical pain alone. It can be

问题 i have an equation , ((a*b*c*d)/(e*f*g*h))%m My question is , Can i first apply multiplication property (a*b) mod(n) = (a*mod(n)) * (b*mod(n) ) mod(n) to numerator and then denominator , so that numerator and denominator becomes a single value , and then solve the division operation? (a/b) mod(n) = (a*inv(b)) mod(n) 回答1: Let N = a*b*c*d and D = e*f*g*h . We want to calculate: (N/D) mod n = (N * inv(D)) mod n We can use the multiplication property here in the following way: (N * inv(D)) mod n

问题 I am having trouble recreating and imagining how to recreate the following piece of vanilla Javascript code in Angular2 (I just typed it out on the spot so don't worry about syntax or logic errors). As you can see, I am looping through an array of products and if the iteration modulus of 4 then I close the div with class 'row' and start a new div with a class of row. This is so I can add 'col-xs-3 col-sm-3 col-md-3 col-lg-3' classes onto the products to make them responsive. <div class='row'>

问题 I'd searching many websites trying to understand how does RSA works. I have a modulus "A89F25A56FA6DA258C8CA8B40427D927B4A1EB4D7EA326BBB12F97DED70AE5E4480FC9C5E8A972177110A1CC318D06D2F8F5C4844AC5FA79A4DC470BB11ED635699C17081B90F1B984F12E92C1C529276D8AF8EC7F28492097D8CD5BECEA16FE4088F6CFAB4A1B42328A1B996F9278B0B7E3311CA5EF856C2F888474B83612A82E4E00D0CD4069A6783140433D50725F" and exponent "03" and i have to decrypt information formated in hex bytes. My questions are: How do i create a public

问题 This seems to be the #1 thing that is asked when dealing with Remainder/Mod, and I'm kind of hitting a wall with it. I'm teaching myself to program with a textbook and a chuck of C code. Seeing as I don't really have an instructor to say, "No, no. It actually works like this", I thought I'd try my hand here. I haven't found a conclusive answer to the mathematical part of this, though. So... I'm under the impression that this is a pretty rare occurrence, but I'd still like to know what it is

问题 I don't have any trouble grabbing a list of elements and sorting them alphabetically, but I'm having difficulty understanding how to do it with a modulus. ### UPDATE ### Here's the code working 'my way', however, I like the re-usability of the answer provided below more, so have accepted that answer. <script type="text/javascript"> $(document).ready( function() { $('.sectionList2').each( function() { var oldList = $('li a', this), columns = 4, newList = []; for( var start = 0; start < columns

问题 I am new to Java, actually programming in general. I understand that the modulus operator (%) returns the remainder of two numbers, however, I do not understand why 17 % 40 = 17. I understand that 40 % 17 = 6, and 17 % 5 = 2, and 40 % 5 = 0. I get the gist of what value is returned as the remainder. But 17 % 40 = 17 has me stumped. The only rationalization I can devise is that since the remainder is less than 1 the total value 17 is returned, why not 0? Please help to explain this enigma to

问题 The part I keep getting stuck on is boolean(0 % 2 !=0) == false. I mean if 2 goes into 0, 0 times then the remainder would be 2, and 2 does not equal 0. So it should be true. Yet but when I put the boolean in my java program it is treating it as false. Anyone know why? The only logical answer I can wrap my head around is that maybe integers go into 0 and infinite number of times and so are recognized as false, anyone? 回答1: There are two steps: 0 % 2 evaluates to 0 . 0 != 0 evaluates to false
