   4 days ago · In this type of approach, we use the bitwise XOR operation. We use the property i.e. a ^ b ^ a = (a ^ a) ^ b = 0 ^ b = b. Using this property, we are going to XOR all the array elements and the numbers from 1 to 100, from which the missing number will be the result. While approaching the problem through this method, user must need to remember ...
