 Here's a Python program that says to write a Symmetric array transformation. A top interview question. Symmetric Array Transformation Problem: Write a Python function that transforms a given array into a symmetric array by mirroring it around its center. For example: Input: [1, 2, 3] Output: [1, 2, 3, 2, 1] Hints: Use slicing for the reverse part. Concatenate the original array with its mirrored part. Example def symmetric_array(arr):     """     Transforms the input array into a symmetric array by mirroring it around its center.     Parameters:     arr (list): The input array.     Returns:     list: The symmetric array.     """     # Mirror the array by concatenating the original with its reverse (excluding the last element to avoid duplication)     return arr + arr[-2::-1] # Example usage input_array = [1, 2, 3] symmetric_result = symmetric_array(input_array) print("Input Array:", input_arr...

How to Write Recursive Shell Script in Bash Terminal

Here's a simple bash recursive function. To write it, you can use JavaScript and other scripting languages. Below is the example that shows you how to write a recursive function in the bash shell. Recursive function Precisely, calling the same function within it is called the Recursive function. We call itself and its contents.  Moreover, the recursive functions go in the loop due to self-calling. While writing the code, ensure it has a condition that breaks the loop. Recursive logic #!/bin/bash for ((i = 1; i < 65; i++)) { ((arr[i - 1] = i)) } i = 1; key = 8 function linear_search { echo "Element value: ${arr[$i-1]}" if ((arr[i - 1] == key)) then echo "Linear search found $key on attempt $i" return 0 => it breaks the loop else ((i++)) linear_search = > Calling th same script fi } linear_search = > Calling the same script Output Here is the dissection of the output. Displayed the array's elements until match-condition occurs. In the end, a displa...
