Minimum subarray reversals required to make given binary array alternating | Function to count minimum subarray reversal operations required to make array alternating.
Stores minimum count of operations required to make array alternating.
Traverse the array.
If arr [ i ] is greater than arr [ i + 1 ].
Update cntOp.
