Given an array A [] consisting of 0’s and 1’s. A flip operation is one in which you turn 1 into 0 and a 0 into 1. You have to do at most one “Flip” operation of any subarray. Formally, select a range (l, r) in the array A [], such that (0 ≤ l ≤ r < n) holds and flip the elements in this range to get the maximum ones in ... Webattention, namely, the Bit-Flip based adversarial weight at-tack, aka. Bit-Flip Attack (BFA). BFA has shown extraor-dinary attacking ability, where the adversary can malfunc-tion a quantized Deep Neural Network (DNN) as a random guess, through malicious bit-ﬂips on a small set of vulnera-bleweightbits(e.g., 13outof93millionsbitsof8-bitquan- how is a business taxed
