Merge Arrays in Ruby Using the Array concat() Method To merge two arrays in Ruby, we can use the concat() method, which allows us to combine the elements of two arrays into a single array. The concat() method is invoked on an array and takes another array as an argument. The element...

Introduction to Merge Sort in C Merge sort is a sorting technique used for most of the problem solving related to sorting elements. Merge sort in C is related to the divide and conquer paradigm, which divides the input array into two arrays of different sizes which further calls the two div...
In vanilla JavaScript, there are multiple ways to combine all elements of two arrays and returns a new array. You can either use the Array.concat() method or the spread operator (...) to merge multiple arrays. The Array.concat() takes in one or more arrays as input and merges all ...
