In programming languages, we have various data types to store different types of data. Some of the most used data types are integer, string, float, and boolean. The boolean data type is a type of data that stores only two types of values i.e. True or False. These values are not case-sensitive depending upon programming languages. The name Boolean comes from the branch of mathematics called Boolean algebra, named after George Bool the mathematician....

In this article, we will use JSON data to communicate between two programs called C++ and Node.js. We can use a common text format to communicate, but text format will contain a lot of complexities. However, JSON is lightweight and easy to use. JSON is language-independent and hence can be used by any programming language....

This assertion will return true in the case if either given filename exists and is writable else return false. In case of true the asserted test case got passed else test case got failed....

Given an integer x, the task is to find if every k-cycle shift on the element produces a number greater than or equal to the same element. A k-cyclic shift of an integer x is a function that removes the last k digits of x and inserts them in its beginning. For example, the k-cyclic shifts of 123 are 312 for k=1 and 231 for k=2. Print Yes if the given condition is satisfied else print No.Examples:...
