GIT Knowledge

#1 Git author Unknown
Sets the name of the user for all git instances on the system
$ git config --global user.name "Firstname Lastname"
$ git config --global user.email "your_email@youremail.com"
[user]
name = Bob Gilmore
email = me@mydomain.com
3.3  get remote server  branch info
3.4  switch to branch
#4  Git  fetch
-- cache the info entered
#6 Git check out
#7 Git pull
 you have to tell git where to pull from, in this case from the current directory/repository:
git pull . master  but when working locally, you usually just call merge (pull internally calls merge):
git merge master#8 git git-credentials
#9 git merge

Solution:  Or even better than running git config, you can edit your ~/.gitconfig file directly. Look and see if there's a section for [user] with the relevant information. For example, my ~/.gitconfig has this... (There's no space in front of the [user], and single tabs in front of the name and email labels) If it doesn't have those set properl…

Top 10 Algorithms for Coding Interview

http://www.programcreek.com/2012/11/top-10-algorithms-for-coding-interview/

The following are top 10 algorithms related concepts in coding interview. I will try to illustrate those concepts though some simple examples. As understanding those concepts requires much more effort, this list only serves as an introduction. They are viewed from a Java perspective and the following concepts will be covered: StringLinked ListTreeGraphSortingRecursion vs. IterationDynamic ProgrammingBit ManipulationProbabilityCombinations and PermutationsOther problems that need us to find patterns I will keep updating this list to add more classic problems and problems from Leetcode. 1. String Unlike in C++, a String is not a char array in Java. It is a class that contains a char array and other fields and methods. Without code auto-completion of any IDE, the following methods should be remembered. toCharArray()//get char array of a StringArrays.sort()//sort an arrayArrays.toString(char[] a)//convert to string c…
