HackerEarth Roy and Symmetric Logos problem solution

YASH PAL, 31 July 202414 February 2026
In this HackerEarth Roy and Symmetric Logos problem solution, Roy likes Symmetric Logos.
 
How to check whether a logo is symmetric?
Align the center of logo with the origin of Cartesian plane. Now if the colored pixels of the logo are symmetric about both X-axis and Y-axis, then the logo is symmetric.
 
You are given a binary matrix of size N x N which represents the pixels of a logo.
1 indicates that the pixel is colored and 0 indicates no color.
 
For instance: Take a 5×5 matrix as follows:
 
01110
01010
10001
01010
01110
