You are to encrypt some data using the ECB, CBC, and CTR modes of operation. The permutation is p : {0,1}⁴ {0,1}⁴ defined as p(x) = (x >>> 1), ie, rotate x RIGHT 1 bit. If you need an IV use 1001. If you need a nonce use 11. If you need a padding method use 10*. If you need a counter use all available space and begin at 0. Do not include any IV or nonce in your output.

Encrypt 1010 0101 1 by writing the output in four-bit chunks. If needed, the last chunk can be shorter than four bits. Use only the digits 0 and 1 with no added spaces or formatting.
