Topcoder Fenwick Tree Code Example

Example: dfenwick tree code c++ // C++ code to demonstrate operations of Binary Index Tree # include <iostream> using namespace std ; /* n --> No. of elements present in input array. BITree[0..n] --> Array that represents Binary Indexed Tree. arr[0..n-1] --> Input array for which prefix sum is evaluated. */ // Returns sum of arr[0..index]. This function assumes // that the array is preprocessed and partial sums of // array elements are stored in BITree[]. int getSum ( int BITree [ ] , int index ) { int sum = 0 ; // Iniialize result // index in BITree[] is 1 more than the index in arr[] index = index + 1 ; // Traverse ancestors of BITree[index] while ( index > 0 ) { // Add current element of BITree to sum sum += BITree [ index ] ; // Move index to parent node in getSum View index -= index & ( - index ) ; } return su

C: Linux Command Executed By Popen() Function Not Showing Results

Answer : Since the output is going to stderr you need to redirect stderr like so: FILE* file = popen("ntpdate 2>&1", "r"); this will redirect stderr to stdout and so you will see output from both. Second issue fscanf will stop at the first space so you can replace with fgets : fgets(buffer, 100, file); As Shafik Yaghmour correctly diagnosed, the output you see from ntpdate is written (correctly) to its standard error, which is the same as your programs standard error. To get the error messages sent down the pipe, use: FILE *file = popen("ntpdate 2>&1", "r"); That sends the standard error output from ntpdate to the standard output of the command, which is the pipe you're reading from. Of course, it looks like using ntpdate isn't going to work well until you've configured something.

Can You Check If A PSN Code Is Valid Without Redeeming It?

How To Append String In Javascript Code Example

Example 1: string concatenation in js var str1 = "Hello " ; var str2 = "world!" ; var res = str1 . concat ( str2 ) ; console . log ( res ) ; Example 2: how to concatenate strings javascript var str1 = "Hello " ; var str2 = "world!" ; var res = str1 . concat ( str2 ) ; // does not change the existing strings, but // returns a new string containing the text // of the joined strings. Example 3: string concat javascript //This method adds two or more strings and returns a new single string. let str1 = new String ( "This is string one" ) ; let str2 = new String ( "This is string two" ) ; let str3 = str1 . concat ( str2 . toString ( ) ) ; console . log ( "str1 + str2 : " + str3 ) output : str1 + str2 : This is string oneThis is string two Example 4: js concatenate strings const str1 = 'Hello' ; const str2 = 'World' ; console . log ( str1 + str2 ) ; >> HelloWorl

CP Command Prompt Windows 7 Not Recognized

Answer : By default , there's no cp in Windows Command Prompt (cmd.exe). The equivalent cmd.exe command is copy . cp is a Unix command. If you can use PowerShell instead, which should come pre-installed in modern Windows systems, you can use cp and some other Unix commands directly in it. If PowerShell isn't an alternative, you can use cp directly in Windows Command Prompt if you install Cygwin. Moreover, Cygwin also includes the rsync command, which has many more features than cp , and might be preferable if you're not just copying a single file (e.g. for backup purposes). it is a unix/linux command. Download the cygwin package from cygwin.com Necromancing. There's a way to do run cp without cygwin and powershell and without admin rights. Download the respective package (CoreUtils) from the Gnu-Win32 package repository. You need the zipped binaries and the zipped dependencies. Unpack, and copy bin from deps to bin from coreutils. Now add the bin folder to the p

Convert List To IEnumerable

Answer : Maybe try this? ( untested ) ViewBag.AvaiableEnums = dynamicTextEnumsAvaiable.Select(x => new SelectListItem() { Text = x.ToString() }); You could do the following ViewBag.AvaiableEnums = new SelectList(dynamicTextEnumsAvaiable) See http://msdn.microsoft.com/en-us/library/system.web.mvc.selectlist(v=vs.118).aspx You can maybe use a Linq statement to convert it IEnumerable<SelectListItem> myCollection = dynamicTextEnumsAvaiable .Select(i => new SelectListItem() { Text = i.ToString(), Value = i });

CPU-Z Says My PC3-10600 1333MHz RAM Is Actually PC3-10700 667MHz. Do I Have 1333 Or 667 MHz RAM?

Answer : You have 1333 DDR (Double Data Rate) RAM. The RAM itself runs at 666MHz, but because it is "double pumped" its equivalent data rate is twice that, hence 1333MHz. You do indeed have PC3-10600. CPU-Z shows only the half of it because DDR RAM like the names says - Double Data Rate - can transfer twice as much data on one I/O bus clock, than the actual IO frequency which CPUZ shows. If you want to dig deeper in this topic check this link, it describes it really well. Actually its not 10600 but 10700 as the OP says. and it runs at 1334 (2x667) to be exact. Sisoft Sandra measures the same as the description.
