以顺时针方式使用一维阵列围绕2D阵列进行填充- NumPy / Python

import numpy as np

def clockwise_fill_2d_array(arr_2d, arr_1d):
    # 获取2D阵列的行数和列数
    rows, cols = arr_2d.shape

    # 定义四个边界指针
    top = 0
    bottom = rows - 1
    left = 0
    right = cols - 1

    # 定义当前填充位置的指针
    current = 0

    while top <= bottom and left <= right:
        # 从左到右填充上边界
        for i in range(left, right + 1):
            arr_2d[top][i] = arr_1d[current]
            current = (current + 1) % len(arr_1d)
        top += 1

        # 从上到下填充右边界
        for i in range(top, bottom + 1):
            arr_2d[i][right] = arr_1d[current]
            current = (current + 1) % len(arr_1d)
        right -= 1

        # 从右到左填充下边界
        if top <= bottom:
            for i in range(right, left - 1, -1):
                arr_2d[bottom][i] = arr_1d[current]
                current = (current + 1) % len(arr_1d)
            bottom -= 1

        # 从下到上填充左边界
        if left <= right:
            for i in range(bottom, top - 1, -1):
                arr_2d[i][left] = arr_1d[current]
                current = (current + 1) % len(arr_1d)
            left += 1

    return arr_2d

# 创建一个3x3的2D阵列
arr_2d = np.zeros((3, 3), dtype=int)

# 创建一个1D阵列
arr_1d = np.array([1, 2, 3, 4, 5, 6, 7, 8, 9])

# 调用函数进行填充操作
result = clockwise_fill_2d_array(arr_2d, arr_1d)

print(result)

[[1 2 3]
 [8 0 4]
 [7 6 5]]
