Flip the bits codeforces solution
WebYou 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 the final array. You can possibly make zero operations to … WebThis will contain the solution of codeforces problems solved by me - codeforces-solutions/B_Flip_the_Bits.cpp at main · mjmanas54/codeforces-solutions

In one operation, you can select any prefix of a a with an equal number of 0 0 and 1 1 symbols. Then all symbols in the prefix are inverted: each 0 0 becomes 1 1 and each 1 1 becomes 0 0.
WebInitially the answer is 0. At first we will try to make the highest bit in the answer into 1 (I think this doesn’t need a proof). If we want the i − th bit in the answer to be 1, we need for every element of c the i − th bit to be 1 and for this in every optimal pair we need (ai & (1 ≪ i)) ⊕ (bi & (1 ≪ i)) = (1 ≪ i).
