3. 接下来是8,7.要考虑matrix不为空,因为是从matrix最后一行,从最后一个元素pop 4. 最后是4,5.因为是最后两个元素,所以其他元素应该已经被pop出去了,所以这里相当于是从matrix最后一行开始从左到右pop(0),循环,用append Spiral Matrix II(LC59) Given an integern, generate a square matrix filled with e...
result.append(matrix[row][lastCol]) for col in range(lastCol, firstCol, -1): result.append(matrix[lastRow][col]) for row in range(lastRow, firstRow, -1): result.append(matrix[row][firstCol]) return result Spiral Matrix II Given an integer n, generate a square matrix filled with e...
