function calculateStepCount(inputMatrix, outputMatrix) { // Flatten the matrix into a single array for easier processing const inputFlat = inputMatrix.flat(); const outputFlat = outputMatrix.flat(); // Calculate the number of elements that are in the correct position let numCorrect = 0; for (let i = 0; i < inputFlat.length; i++) { if (inputFlat[i] === outputFlat[i]) { numCorrect++; } } // Calculate the number of steps required to solve the puzzle const steps = (inputFlat.length - numCorrect) / 2; return steps; } // Test cases console.log(calculateStepCount([[1,2,3],[5,4,6],[7,8,9]], [[1,2,3],[4,5,6],[7,8,9]])); // Output: 1 console.log(calculateStepCount([[1,2,3],[4,5,6],[7,8,9]], [[1,2,3],[4,5,6],[7,8,9]])); // Output: 0

According to my knowledge, the above code is correct for the following problem. but after running this code it returns an error message that I mention below. find me what should I do.

"message: The answer should be valid for any given input."

Below is the solution to the 3x3 matrix puzzle. Using javascript, calculate the least number of steps required to solve the puzzle and print the solved puzzle. Input can be any combination of numbers from 1-9 placed in a 3x3 matrix. To solve the puzzle you can only interchange/ switch numbers and each switch is calculated as a step.

[1,5,6] [3,2,7] [8,4,9]

Return type should be a number.

JavaScript

calculateStepCount([[1, 2, 3], [5, 4, 6], [7, 8, 9]], [[1, 2, 3], [4, 5, 6], [7, 8, 9]]); // should return 1 calculateStepCount([[1, 2, 3], [4, 5, 6], [7, 8, 9]], [[1, 2, 3], [4, 5, 6], [7, 8, 9]]); // should return 0

The answer should be valid for any given input.

What have you tried?

Where are you stuck?

What help do you need?

Use the "Improve question" widget to edit your question and provide better information.

We have no idea what test cases do and don't work, or what it produces when it does / doesn't function.

We have no idea what you have tried to find out where it is failing, or why - we don't even know if you have tested it yourself or just submitted it and hoped for the best!

So tell us what you have done; what you tried to find out why it doesn't work; when it does and doesn't work.

And all you have done in the commente is repeated the original question!

I am stuck with what should I do to fulfill final test case

I'm not being funny or awkward here, you must have done something.

What does the debugger show you is going on? Have you tried it?

Return type should be a number.

calculateStepCount([[1, 2, 3], [5, 4, 6], [7, 8, 9]], [[1, 2, 3], [4, 5, 6], [7, 8, 9]]); // should return 1

calculateStepCount([[1, 2, 3], [4, 5, 6], [7, 8, 9]], [[1, 2, 3], [4, 5, 6], [7, 8, 9]]); // should return 0

the answer should be valid for any given input.

in my assignment, I have to fulfill these four and get a tick mark for all the above cases separately. In my code, the tick mark falls on the first three. The last one is not complete. That's why I asked you what I need to change in my code for that.
