Project sample inputs - FLIP (all 6)

11:36am Fri 27th Sep, Alistair L.

I was examining the sample inputs provided for the FLIP question of the project after getting an incorrect answer to search for possible bugs in my code. Looking over sample input 1 I visually identified 3 distinct 8-connected regions of each colour, however the answer given for this input is only 2. Attached is a graphic representation of the input. Is this an error in the sample or am I misunderstanding the problem in some way and need to go back to read it again more closely?

You flip the white space then it'll become a big black space with the other 3 black space. Then flip the big black space and it'll all become white

Forgot to mention, any white space in the middle that isn't (0,0) or the last row.

The other student who has replied is correct. It seems you misunderstood the problem statement and need to read it again more closely.

So once you flip a segment, you can return to the grid's beginning to revisit?
