range

I want to use a switch statement to check a range of numbers I have found a few places saying something like case 1...5 or case (score >= 120) && (score <=125) would work but I just somehow keep on getting errors. What I want is if the number is between 1600-1699 then do something. I can do if statements but figured it's time to start using switch if possible. On the JVM level switch statement is fundamentally different from if statements. Switch is about compile time constants that have to be all specified at compile time, so that javac compiler produces efficient bytecode. In Java switch

What is the correct response to a GET request with the header field Range: bytes=278528- if Range is not supported? Reading the HTTP header definitions ( http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html ) i think i should at least set: Accept-Ranges: none , but it clearly states that Clients MAY generate byte-range requests without having received this header for the resource involved. So, if a client requests a range, should I: Reply with the whole file from byte 0? Reply with some status error? (400/406/416/501) see: http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html You may ignore

I am trying to solve Project Euler problem #12: The sequence of triangle numbers is generated by adding the natural numbers. So the 7th triangle number would be 1 + 2 + 3 + 4 + 5 + 6 + 7 = 28. The first ten terms would be: 1, 3, 6, 10, 15, 21, 28, 36, 45, 55, ... Let us list the factors of the first seven triangle numbers: 1: 1 3: 1,3 6: 1,2,3,6 10: 1,2,5,10 15: 1,3,5,15 21: 1,3,7,21 28: 1,2,4,7,14,28 We can see that 28 is the first triangle number to have over five divisors. What is the value of the first triangle number to have over five hundred divisors? Here's the solution that I came up

I'm having a serious problem with MySQL (innoDB) 5.0. A very simple SQL query is executed with a very unexpected query plan. The query: SELECT SQL_NO_CACHE mbCategory.* FROM MBCategory mbCategory INNER JOIN ResourcePermission as rp ON rp.primKey = mbCategory.categoryId where mbCategory.groupId = 12345 AND mbCategory.parentCategoryId = 0 limit 20; MBCategory - contains 216583 rows ResourcePermission - contains 3098354 rows. In MBCategory I've multiple indexes (columns order as in index): Primary (categoryId) A (groupId,parentCategoryId,categoryId) B (groupId,parentCategoryId) In

This question has already been asked but until now there is no working answer so I am tempting to open it again hopefully we can find a hack to it. I have a contentEditable paragraph and a text input, when I select some text and click the input, the selection is gone. So I've tried to save the selection on input mousedown and to restore it back on mouseup and yeah it works ( as expected in firefox) But... in chrome the input lose focus :( See it in action ( use chrome ) : https://jsfiddle.net/mody5/noygdhdu/ this is the code I've used : HTML <p contenteditable="true"> Select something up here

given a Math.random() function which returns a number between [0,1) and min max values to specify the range, how can we generate numbers for the following cases: Case we want integer : A: (min,max) ? B: [min,max) return Math.floor(Math.random() * (max - min)) + min; C: (min,max] ? D: [min,max] return Math.floor(Math.random() * (max - min + 1)) + min; Case we want float : A: (min,max) ? B: [min,max) return Math.random() * (max - min) + min; C: (min,max] ? D: [min,max] ? Integers Your formula for B. is correct, everything else is obtained by trivial +1 -1 corrections: A. (min, max) = [min + 1,

I'm trying to determine range of the various floating-point types. When I read this code: #include <stdio.h> main() { float fl, fltest, last; double dbl, dbltest, dblast; fl = 0.0; fltest = 0.0; while (fl == 0.0) { last = fltest; fltest = fltest + 1111e28; fl = (fl + fltest) - fltest; } printf("Maximum range of float variable: %e\n", last); dbl = 0.0; dbltest = 0.0; while (dbl == 0.0) { dblast = dbltest; dbltest = dbltest + 1111e297; dbl = (dbl + dbltest) - dbltest; } printf("Maximum range of double variable: %e\n", dblast); return 0; } I don't understand why author added 1111e28 at fltest
