For a stream S = z1, . . . , z2n of 2n integers in [n], we call j [n] a duplicative element if it occurs more than once. Prove that S must contain a duplicative element, and design an algorithm that takes in S as input and with probability at least 1 1 n outputs a duplicative element. Your algorithm may use at most polynomial in log n space. Prove the correctness and analyze the space complexity of your algorithm. Your algorithm may only take a single pass of the stream
