A run is a consecutive sequence of repeated values or observations. For repeated values, R's "run-length encoding" concisely describes a vector in terms of its runs. Consider: dat <- c(1, 2, 2, 2, 3, 1, 4, 4, 1, 1) We have a length-one run of 1s; then a length-three run of 2s; the...

KVC :- Key-Value Coding Normally instance variables are accessed through properties or accessors but KVC gives another way to access variables in form of strings. In this way your class acts like a dictionary and your property name for example “age” becomes key and value that property holds becom...

What is UTF-8? UTF-8 is an encoding, which is variable-length and uses 8-bit code units - that's why UTF-8. In the internet UTF-8 is dominant encoding (before 2008 ASCII was, ehich also can handle any Unicode code point.). Is UTF-8 the same as Unicode? "Unicode" isn't an encoding - i...

I would recommend to a beginner to start with this style of coding. And if anybody can suggest a better way(p.s i opted this technique and is working efficiently for me in an app used by more then 100k users), feel free for any suggestions. TIA.

What is an encoding and how it works? A computer can't store letters or anything else - it stores bits. Bit can be either 0 or 1 ("yes"/"no", "true"/"false" - these formats are called binary therefore). To use these bits some rules are required, to convert ...

When an email client doesn't support media-queries, a hybrid approach can be used to to reconfigure the layout for different screen sizes for email clients regardless of media query support. It uses fluid tables and max-width and min-width to impose rigid baselines (allowing some movement) and impos...

Math is one subject that a lot of students find challenging. Fortunately, students can now use coding to help them out. Coding, which is also called computer programming, is a process where one performs specific computations by building and designing executable computer programs. Many students these...

5 Best Strategies to Teach Your Students Coding As The Mercury News can probably tell us, the extensive field of technology will come to include more and more coding as time advances. Being a teacher, it might be in your area of expertise to pass on your knowledge to students. But we know, this may ...
