如何查找与数组的距离

def find_distance(arr, target):
    min_distance = float('inf')  # 初始化最小距离为正无穷大
    min_index = -1  # 初始化最小距离对应的索引为-1

    for i in range(len(arr)):
        distance = abs(arr[i] - target)  # 计算距离
        if distance < min_distance:
            min_distance = distance
            min_index = i

    return min_distance, min_index
