I interviewed with Google for initial Screening. Though I was rejected, thought to share the problem with the community.

Given a binary matrix, tell if it is posible to convert entire matrix to zeroes using below operations :

1. flip entire column

2. flip entire row

   Input :
   [[0,0,1,0],
   [1,1,0,1],
   [0,0,1,0],
   [1,1,0,1]]

   Output : Yes
   [[0,0,0,0],
   [0,0,0,0],
   [0,0,0,0],
   [0,0,0,0]]
