JavaScript
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."

question

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 I have tried:

JavaScript
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

And?
What have you tried?
Where are you stuck?
What help do you need?

No, you have just copy'n'pasted your assignment, shown us a lump of code and said "it don't work".

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 have developed the code and

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 these test cases are fulfill.

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

And? What have you tried to do to find out why?

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?
