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.

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:

<pre>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
