Can I get the forest at the specified index of a BigInteger
Hi, I added two BigInteger each for a binary number in this way://x and y are StringBuilder object having large binary number on each
BigInteger a = new BigInteger(x.toString(), 2);
BigInteger b = new BigInteger(y.toString(), 2);
BigInteger c = a.add(b);
Now I need to know the value of index data bit in BigInteger c. For that, I am to convert c to binary string using the c.toString (2); then I use string.charAt (index); method. Sounds pretty good, but the last binary conversion BigInteger didn't use that much, because I just need to know the forest, not the binary integer. This can improve the program. Is there a better way to achieve the same?Thank you
Check the "testBit' BigInteger method. (I did not know that casual, just watched all the methods available in BigInteger, and this looks like what you want.)

All my old tabs are missing after a crash. I chose "view my tabs, windows and last time ', like the start option. Many unwanted changes in tab management happened recently. For example when I close a tab in a window of the two tab, I see a blank screen (see picture). Preview display seems to be broken (see attachment). How can I get the old behaviour back?
After researching the issue, it seems that the problem was a problem of NoScript configuration. After restoring NoScript to the default values, the tab number disappeared.
Thanks for your help.

I can not get the norton for 36 firefox toolbar. Have run Norton live update repeatedly. He updated of all good and applied a patch. When I go to the firefox menu > Modules > extensions, toolbar Norton is grayed out and says he is not compatible with firefox 36 and is disabled. Help! I need my Norton safe.
Hi Cathie7372, according to Norton the latest version of the toolbar is compatible with firefox 36 is 2014.7.10.26 - your watch as 2014.7.10. 16...
as norton distributes the updates themselves we are probably not able to help much - please contact norton support if you do not receive the last update, even after running liveupdate repeatedly. they should be able to help get their product to date.

When pairing manually, you must press the name of 5 digits on the screen of your iPhone (when he shows the same device name that is shown on your watch, after typed it on your watch's 'i'):
Your watch then displays a six-digit code, you will then enter on your iPhone:
