Solution in JS: function getNumberSwaps(arr, arrMap, sortedArr) { let numberOfSwaps = 0; for (let i = 0; i < sortedArr.length; i++) { if (sortedArr[i] !== arr[i]) { const tmp = arr[i]; const idxSource = arrMap[sortedArr[i]];

        arr[i] = arr[idxSource];
        arr[idxSource] = tmp;

        arrMap[tmp] = idxSource;
        arrMap[sortedArr[i]] = i;

        numberOfSwaps++;
    }
}

return numberOfSwaps;

}

function lilysHomework(arr) { const ascArr = arr.toSorted((a, b) => a - b); const descArr = arr.toSorted((a, b) => b - a);

const arrMap = {};
arr.forEach((num, idx) => {
    arrMap[num] = idx
});
return Math.min(getNumberSwaps([...arr], { ...arrMap }, ascArr), getNumberSwaps(arr, arrMap, descArr));

}
