You may want to do this if the remote repository is migrated. The command for changing the remote url is: git remote set-url It takes 2 arguments: an existing remote name (origin, upstream) and the url. Check your current remote url: git remote -v origin https://bitbucket.com/develop/myrep...

Let's say we have a problem of size n. Now for each step of our algorithm(which we need write), our original problem becomes half of its previous size(n/2). So at each step, our problem becomes half. StepProblem1n/22n/43n/84n/16 When the problem space is reduced(i.e solved completely), it cannot ...

A higher-order function, as opposed to a first-order function, can have one of three forms: One or more of its parameters is a function, and it returns some value. It returns a function, but none of its parameters is a function. Both of the above: One or more of its parameters is a fu...

If we have a c++ project that uses a config.h configuration file with some custom paths or variables, we can generate it using CMake and a generic file config.h.in. The config.h.in can be part of a git repository, while the generated file config.h will never be added, as it is generated from the cu...

Basic foreground images can be inserted into an email document just like they are for web pages: <img src="http://www.yourserver.com/email/images/logo.png"> And they can be made links by wrapping them in an <a href> tag: <a href="http://www.yourwebsite.com"&gt...

The series of events here is supposed to work as follows: Compile code with -pg option Link code with -pg option Run program Program generates gmon.out file Run gprof program To add profiling flags, you must add to your CMakeLists.txt: SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -pg&quot...

You can use Map<String, List<String>> myMap = new HashMap<>(); instead of Map<String, List<String>> myMap = new HashMap<String, List<String>>(); However, you can't use List<String> list = new ArrayList<>(); list.add("A"); ...

If you are using Windows open Git Bash. If you are using Mac or Linux open your Terminal. Before you generate an SSH key, you can check to see if you have any existing SSH keys. List the contents of your ~/.ssh directory: $ ls -al ~/.ssh # Lists all the files in your ~/.ssh directory Check...

If shift is called outside of a delimiting reset block, it can be used to create functions that themselves create continuations inside a reset block. It is important to note that shift's type is not just (((A => B) => C) => A), it is actually (((A => B) => C) => (A @cpsParam[B, C])...

We can have three cases to analyze an algorithm: Worst Case Average Case Best Case #include <stdio.h> // Linearly search x in arr[]. If x is present then return the index, // otherwise return -1 int search(int arr[], int n, int x) { int i; for (i=0; i<n; i...

Not everything in a bindings library will have the same name in C# as it does in Java. In C#, interface names start with "I", but Java has no such convention. When you import a Java library, an interface named SomeInterface will become ISomeInterface. Similarly, Java doesn't have propert...

For simple cases, you can filter data directly. a = np.random.normal(size=10) print(a) #[-1.19423121 1.10481873 0.26332982 -0.53300387 -0.04809928 1.77107775 # 1.16741359 0.17699948 -0.06342169 -1.74213078] b = a[a>0] print(b) #[ 1.10481873 0.26332982 1.77107775 1.16741359 0.176999...

The if statement is a conditional statement that allows a program to enter or not a specific section of code depending if the condition(s) of the statement are met or not. It can be found in mostly all the existing programming languages. The if statement will usually take the following shape: if(s...

A statement is usually a test on a variable or the return value of a function. To test those values, we can use some relational operators: OperatorMeaningExample==Equal to1 == 1 is TRUE, 1 == 2 is FALSE!=Not equal to1 != 2 is TRUE, 1 != 1 is FALSE<Less than1 < 2 is TRUE, 2 < 1 is FALSE>...
