1. a = 3 , b= 5

2. a = 400, b= 134

3. a = 228, b = 57

    Can someone please help me for this assignment? Cryptography — the science of secret writing — is an old science; the first recorded use was well before 1900 B.C. An Egyptian writer used previously unknown hieroglyphs in an inscription. We will use a simple substitution cypher called rot13 to encode and decode our secret messages. ROT13 ("rotate by 13 places", sometimes hyphenated ROT-13) is a simple letter substitution cipher that replaces a letter with the 13th letter after it, in...
