JS数组-将一维数组重新组织为二维数组，其中N组按顺序放值

function reshapeArray(arr, rows, cols) {
    if (arr.length !== rows * cols) {
        throw new Error('Invalid dimensions');
    }
    let result = [];
    for (let i = 0; i < rows; i++) {
        result[i] = [];
        for (let j = 0; j < cols; j++) {
            result[i][j] = arr[i * cols + j];
        }
    }
    return result;
}

// 示例用法
let oneDimensionalArray = [1, 2, 3, 4, 5, 6];
let twoDimensionalArray = reshapeArray(oneDimensionalArray, 2, 3);
console.log(twoDimensionalArray); // 输出: [[1, 2, 3], [4, 5, 6]]

function reshapeArray(arr, rows, cols) {
    if (arr.length !== rows * cols) {
        throw new Error('Invalid dimensions');
    }
    // 其余代码保持不变
}
