若二维数组int arr[][]={{1,2,3},{4,5,6},{7,8}};,则arr[1][2]的值是( )
举一反三
- 若二维数组int arr[][]={{1,2,3},{4,5,6},{7,8}};,则arr[1][2]的值是( )
- 若二维数组int arr[][]={{1,2,3},{4,5,6},{7,8}};,则arr[1][2]的值是( )
- 若int[][]arr={{1,2,3}},则arr[0][1]的结果为 A: 0 B: 1 C: 2 D: 3
- 如果 frame = [[1,2,3],[4,5,6],[7,8,9]],则rgb = frame[::-1]的值是: A: [[7, 8, 9]] B: [[1,2,3],[4,5,6],[7,8,9]] C: [[7, 8, 9], [4, 5, 6], [1, 2, 3]] D: [[1, 2, 3], [4, 5, 6]]
- 若int[][] arr=new int[][]{{1},{2,3,4},{5,6}},则arr[1][1]的结果为3
