合并来自数组的同步数据并快速排序

function mergeArrays(arrays) {
    return arrays.reduce((acc, curr) => acc.concat(curr), []);
}

function quickSort(arr) {
    if (arr.length <= 1) return arr;
    const pivot = arr[Math.floor(arr.length / 2)];
    const left = [];
    const right = [];
    for (let i = 0; i < arr.length; i++) {
        if (i === Math.floor(arr.length / 2)) continue;
        if (arr[i] < pivot) {
            left.push(arr[i]);
        } else {
            right.push(arr[i]);
        }
    }
    return [...quickSort(left), pivot, ...quickSort(right)];
}

// 示例使用
const arrays = [
    [3, 6, 8],
    [1, 2, 4],
    [5, 7, 9]
];

const mergedArray = mergeArrays(arrays);
console.log("Merged Array:", mergedArray);

const sortedArray = quickSort(mergedArray);
console.log("Sorted Array:", sortedArray);
