LeetCode初级算法-数组-11

题目：旋转图像



C语言解题

void rotate(int** matrix, int matrixRowSize, int *matrixColSizes) {
	int temp;
	for (int i = 0; i < matrixRowSize; i++)
	{
		for (int j = i; j < *matrixColSizes; j++)
		{
			temp = matrix[i][j];
			matrix[i][j] = matrix[j][i];
			matrix[j][i] = temp;
		}
	}
	for (int i = 0; i < *matrixColSizes; i++)
	{
		for (int j = 0; j < matrixRowSize/2; j++)
		{
			temp = matrix[i][j];
			matrix[i][j] = matrix[i][matrixRowSize - j - 1];
			matrix[i][matrixRowSize - j - 1] = temp;
		}
	}
}

将矩阵转置，再将每一行逆序。
