• Nested array permutations in JavaScript

  I recently ran into this problem and couldn't find a solution online:

  How do you compute the nested permutations of an array that contains sub-arrays? This is all the ways to shuffle an array, including shuffling sub-arrays

• Little useless-useful R functions – Using xspline to create wacky signatures

  Nothing short of wacky usage of plot() function with xspline to interpolate the points, but still a “parameter” short of Bezier’s curve.

• Read() Function in C Language

  Practical tutorial on how to use the read() function to read the files and the methods that the C language provides to detect and identify the errors.

• Strings in C Language

  Guide on what a string consists of in the C language, their elements, the kind of data they use, how they are encoded, and what characters each type supports.

• Free() Function in C Language

  Practical tutorial on how to use the free() function to free the dynamically allocated memory using its syntax and the theoretical description of how it works.

• Pthread_Function() in C Language

  Tutorial on how to use the pthread_cancel() function to ask the system to terminate a running thread and how to compile the programs from the pthread library.

• Using Modulus Operator (%) in Bash

  In programming, modulus or remainder is the operation that returns the remainder of a division. In Bash, the modulus operator is represented by the % symbol. The modulus operator is commonly used in programming to check if a number is divisible by another number or to perform operations that require a cyclic pattern.

• How to Calculate Remainder (%) of a Division in Bash

  In programming, finding the remainder of a division is a common task. In Bash, the modulus operator "%" can be used to calculate the remainder of a division. However, the output of the modulus operator can be negative when dealing with negative numbers.
