Check if a Queen can attack a given cell on chessboard

Given the position of the queen (qX, qY) and the opponent (oX, oY) on a chessboard. The task is to determine whether the queen can attack the opponent or not. Note that the queen can attack in the same row, same column and diagonally.
Example: 
 

Input: qX = 4, qY = 5, oX = 6, oY = 7 
Output: Yes 
The queen can attack diagonally.

Input: qX = 1, qY = 1, oX = 3, oY = 2 
Output: No  

Approach: 
 

• If qR = oR, it means that both the queen and the opponent are in the same row and the queen can attack the opponent.
• Similarly, if qC = oC then also the queen can attack the opponent as they both are in the same column.
• And for diagonals, if abs(qR - oR) = abs(qC - oC) i.e. queen can attack the opponent diagonally.

If all of the above conditions fail then the opponent is safe from the queen.

Below is the implementation of the above approach:
 

No
