| Compiling a Linux kernel on Ubuntu | |
| ---------------------------------- | |
| This should be useful in the event that the user wants to investigate whether a newer kernel allows | |
| certain peripherals to work better (or at all) or some other problems they might encounter while using | |
| the kernel officially provided by Canonical. | |
| As an example, I use the 4.1.5 release from kernel.org. | |
| 1) Make sure you have the build environment set up first: |
having a web server turned on doesn't necessarily mean you are serving pages on the world wide web. its what allows you to load your own static files (.html, .js etc.) in a browser via http://.
if you're not sure whether or not you have a web server running, no problem! its easy to confirm.

Given a 2D board and a word, find if the word exists in the grid.
The word can be constructed from letters of sequentially adjacent cell, where "adjacent" cells are those horizontally or vertically neighboring. The same letter cell may not be used more than once.
For example, Given board =
