11. String Conversion Given a binary string consisting of characters '0's and '1', the following operation can be performed it: Choose two adjacent characters, and replace both the characters with their bitwise XOR value. For example, if binaryStr = "1100" and the first two characters are chosen, then after one operation, the string becomes binaryStr = "0000". The goal is to find the minimum number of operations needed to convert all characters of the string to '0'. Example Consider the given binary string to be binaryStr = "101". An optimal sequence of operations is: 1. Select the 1st and 2nd character, then binaryStr = "111". 2. Select the 1st and 2nd character, then binaryStr = "001" 3. Select the 2nd and 3rd character, then binaryStr = "011". 4. Select the 2nd and 3rd character, then binaryStr = "000". pe here to
