Since this question is still getting a lot of attention, I decided to answer it by copying this answer from Code Review.SE: You’re following the same philosophy as the bubble sort, which is very, very, very slow. Have you tried this?: Sort your unordered array with quicksort. Quicksort is much faster than bubble sort (I know, you … Read more
I am trying to get a web service to work which returns a JSON (JAX-RS with jersey implementation on Tomcat). However, I am getting the below exception. I have looked at the similar problems here, but none of the solutions work for me, and it’s been more than half a day 🙁 The resource class … Read more
Copy the contents of the PATH settings to a notepad and check if the location for the 1.4.2 comes before that of the 7. If so, remove the path to 1.4.2 in the PATH setting and save it. After saving and applying “Environment Variables” close and reopen the cmd line. In XP the path does … Read more
In Eclipse, “dead code” is code that will never be executed. Usually it’s in a conditional branch that logically will never be entered. A trivial example would be the following: It’s not an error, because it’s still valid java, but it’s a useful warning, especially if the logical conditions are complex, and where it may … Read more
There you go. This is probably the most trivial example of a function that runs in O(n!) time (where n is the argument to the function):
It’s a combination division-plus-assignment operator. means divide a by b and put the result in a. There are similar operators for addition, subtraction, and multiplication: +=, -= and *=. %= will do modulus. >>= and <<= will do bit shifting.
This error is often resolved by installing a Java version (i.e. 64-bit Java or 32-bit Java) that fits to the type of R version that you are using (i.e. 64-bit R or 32-bit R). This problem can easily effect Windows 7 users, since they might have installed a version of Java that is different than … Read more
The parameter of exit should qualify if the execution of the program went good or bad. It’s a sort of heredity from older programming languages where it’s useful to know if something went wrong and what went wrong. Exit code is 0 when execution went fine; 1, -1, whatever != 0 when some error occurred, you can use different … Read more
Key always should be string. Why it still doesn’t work? Because the error is caused by the redundant brace inside of “elementsToUpdate”. Below is an example:
Goto: Registry-> HKEY_LOCAL_MACHINE-> System-> CurrentControlSet-> Services. Find the concerned service & delete it. Close regedit. Reboot the PC & Re-install the concerned service. Now the error should be gone.
