WebJul 6, 2024 · Input : str = “001” Output : 1 Minimum number of flips required = 1 We can flip 1st bit from 0 to 1 Input : str = “0001010111” Output : 2 Minimum number of flips required = 2 We can flip 2nd bit from 0 to 1 and 9th bit from 1 to 0 to make alternate string “0101010101”. Expected time complexity : O (n) where n is length of input string. WebTask. There are N coins kept on the table, numbered from 0 to N – 1. Initially, each coin is kept tails up. You have to perform two types of operations: 1) Flip all coins numbered between A and B inclusive. This is represented by the command “0 A B”. 2) Answer how many coins numbered between A and B inclusive are heads up.

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 … WebFor example number 10 first appears in the sequence in position 55 (the elements are numerated from one). Find the number on the n -th position of the sequence. Input The only line contains integer n ( 1 ≤ n ≤ 10 14 ) — the position of the number to find. Note that the given number is too large, so you should use 64 -bit integer type to ...
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).
