Step by Step solution about How to resolve the algorithm Array concatenation step by step in the Mathematica / Wolfram Language programming language

The Wolfram language's Join function is used in the provided code to merge two lists: {1,2,3} and {4,5,6}. The resulting list, {1, 2, 3, 4, 5, 6}, is returned.

Here is a step-by-step breakdown of the code:

Join[{1,2,3}, {4,5,6}]: This line of code calls the Join function, which is used to combine multiple lists into a single list. In this case, the Join function is used to combine the lists {1,2,3} and {4,5,6}.

The result of the Join function is a new list, {1, 2, 3, 4, 5, 6}. This new list contains all of the elements from the original two lists, in the order in which they appeared in the original lists.

-> {1, 2, 3, 4, 5, 6}: This line of code simply prints the result of the Join function to the screen.

Join[{1,2,3}, {4,5,6}]

-> {1, 2, 3, 4, 5, 6}
