Technical question:
Given a 2D array with True and False values randomly. Convert the row and column values of True element to True.
Eg:
T F F
F F F
F F F
Resultant matrix:
T T T
T F F
T F F
Start with the basic approach, do not try to optimize from the start itself.
Difficulty of the problem depends on the interviewer, team, and what they are actually looking for. So just take this as an example for reference.
