Problem Statement of Check if Two Chessboard Squares Have the Same Color

You are given two strings, coordinate1 and coordinate2, representing the coordinates of a square on an 8 x 8 chessboard.
Below is the chessboard for reference.

Return true if these two squares have the same color and false otherwise.
The coordinate will always represent a valid chessboard square. The coordinate will always have the letter first (indicating its column), and the number second (indicating its row).

Example 1:

Input: coordinate1 = “a1”, coordinate2 = “c3”
Output: true
Explanation:
Both squares are black.

Example 2:

Input: coordinate1 = “a1”, coordinate2 = “h3”
Output: false
Explanation:
Square “a1” is black and “h3” is white.

Constraints:

coordinate1.length == coordinate2.length == 2
‘a’ <= coordinate1[0], coordinate2[0] <= 'h'
'1' <= coordinate1[1], coordinate2[1] <= '8'

Complexity Analysis

  • Time Complexity: O(1)
  • Space Complexity: O(1)
