An array A contains all the integers from O to n, except for one number which is missing. In this problem, we cannot access an entire integer in A with a single operation. The elements of A are represented in binary, and the only operation we can use to access them is "fetch the jth bit of A[i];' which takes constant time. Write code to find the missing integer. Can you do it in O(n) time?
