Java 实现: classRotateArray{voidleftRotate(intarr[],intk,intn){for(inti=0; i < k; i++) { leftRotateByOne(arr, n); } }voidleftRotateByOne(intarr[],intn){inttemp=arr[0];for(inti=0; i < n-1; i++){ arr[i] = arr[i+1]; } arr[n-1] = temp; } } Python 实现: def...
int arr[] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}; RotateArray ra = new RotateArray(); ra.leftRotate(arr, 8, 12); for (int i = 0; i < arr.length; i++) { System.out.print(arr[i] + " "); } } } Python 实现 def leftRotate(arr, k, n): k = k % ...
Runtime: 48 ms, faster than 94.32% of Python3 online submissions forRotate Array. Memory Usage: 13.5 MB, less than 32.26% of Python3 online submissions for Rotate Array. 以上两组代码相比,运算时间上没有太大的变化;第二个代码少用一个数组的空间,导致空间占用会比较少一些 class Solution: def r...
下面是完整的代码示例,展示了如何使用Python库中的rotate函数来实现图片的顺时针旋转90度: fromPILimportImageimportnumpyasnp# 加载图片image=Image.open("example.jpg")# 将图片转换为numpy数组image_array=np.array(image)# 旋转图片90度rotated_image=np.rot90(image_array)# 将numpy数组转换为PIL图片对象rotate...
# 定义五维点point=np.array([[1,0,0,0,0]])# 旋转30度rotated_point=rotate(point,30,0,1)print("原始点:",point)print("旋转后的点:",rotated_point) 1. 2. 3. 4. 5. 6. 7. 8. 运行这段代码,我们可以看到点的坐标在旋转后是如何改变的。
Array: [ [ 0 1 2 ] [ 3 4 5 ] ] I want this array to be: [ [ 0 3 ] [ 1 4 ] [ 2 5 ] ] It is possible using for loop but that won't be a true numpy coding. python3numpyrotate-arrays 22nd May 2020, 6:34 AM Lerninn ...
【Python-数据分析】 将数组(矩阵)旋转 根据指定的旋转角度 scipy库的rotate方法 关于下列代码说法正确的是? import numpy as np fromscipy.ndimage import rotate a = np.array([[1,2,3,4], [5,6,7,8]]) print('【显示】a:\n',a) print('【执行】rotate(a,angle=90,reshape=True)') ...
```python def rotate_array(arr, n):return arr[n:] + arr[:n]#示例 array = [1, 2, 3, 4, 5]rotated_array = rotate_array(array, 2)print(rotated_array) #输出:[3, 4, 5, 1, 2]```3.图像旋转:对于图像,可以使用图像处理库来实现旋转。例如,在Python中,可以使用PIL库(Pillow库...
Rotate an array of n elements to the right by k steps. For example, with n = 7 and k = 3, the array [1,2,3,4,5,6,7] is rotated to [5,6,7,1,2,3,4]. 大意: 旋转一个有n个元素的数组,右移k步。 比如,n = 7,k = 3,数组 [1,2,3,4,5,6,7] 就被旋转为 [5,6,7...
