2556. Disconnect Path in a Binary Matrix by at Most One Flip

Leetcode Solutions

Count Ones on Diagonal Lines

  1. Initialize an array diag to keep track of the count of ones on each diagonal line.
  2. Iterate over each cell in the matrix and increment the count in diag for the corresponding diagonal line if the cell contains a 1.
  3. Iterate over the diag array, excluding the first and last elements, and check if any count is less than 2.
  4. If a count less than 2 is found, return True as it is possible to disconnect the matrix.
  5. If no such count is found, return False as it is not possible to disconnect the matrix with at most one flip.
