Extracted text: Problem D. DNA Input file: Output file: Time limit: standard input standard output 1 second 256 megabytes Memory limit: As you know desoxyribonucleic acid consists of 4 mucleobases: adenine, guanine, cytosine, thymine. This nucleobases must form pairs: adenine with thymine and guanine with cytosine. You are given the sequence of nucleobases in the first part of DNA spiral. Please, find its second part. Input You are given the only string DNA. It is guaranteed that DNA consists only of uppercase letters 'A', "C', T', 'G'. Output Print the second part of DNA spiral.
