This java program try to count all of the 1 at the rim of the block of 1 surrounded by 0. The

total of the count also includes all the 1 surrounded two pockets of 0 within the block.

The correct answer fro the total count is 154. However, this program gives 167. Where is the fault

of the program?

Expert Solution

The given program logic is not correct.So i re write the program and manually counted the number of ones with that specific conditions.You given the correct answer is 154 , but actually it is 493 and number of such block is 40.[ Manually verified the program output]
