Java Week 9 : Q4
A program needs to be developed which can mirror reflect any 5 × 5 2D character array into its side-by-side reflection. Write suitable code to achieve this
transformation as shown below:
INPUT: OUTPUT:
OOXOO OOXOO OOXOO OOXOO XXXOO OOXXX OOOOO OOOOO XOABC CBAOX
Note the following points carefully
:
1. Here, instead of X and O any character may be present.
2. The input and output array size must be of dimension 5 × 5 and nothing else.
3. Only side-by-side reflection should be performed i.e. ABC || CBA.
