Video 268: In this video, we are going to decode a message

You are given an integer array nums of length n, you want to create an array result of length 2n where result[i] == nums[i] and result[i + n] == nums[i]

Specifically, result is the concatenation of two nums arrays.

In this video, we talked about seven different approaches and the advantage and disadvantage of using those

** Approach 1a: Basic FOR Loop **
Utilize a for loop to append each element twice to the result array.

** Approach 1b: Using WHILE Loop **
Implement a while loop to append elements from nums to the result array until the desired length is achieved.

** Approach 1c: Simplified APPEND Logic **
Start with a copy of nums and append each element from the original nums array.

** Approach 2: Overwrite Zero Array **
Create an array of zeroes with the required length and overwrite it with elements from nums.

** Approach 3: Using Extend Function **
Use the extend method to append all elements of nums to itself.

** Approach 4: Basic Arithmetic **
Concatenate the array with itself using the + operator.

** Approach 5: Multiply the Array **
Use the multiplication operator to duplicate the array.

For a comprehensive understanding and practical demonstration, be sure to watch the entire video. Happy coding!
