Caesar Cipher Encoder Easy AC Ratio: 10.2% (498/4864) asic Types #Loop 14/e se The Caesar cipher (a cipher is a method of encrypting data) is one of the simplest and most widely known encryption techniques. For English text, the Caesar cipher would work by taking each letter in the plaintext message and substituting the letter that is k letters latter (allowing wraparound; that is, having the letter z followed by the letter a) in the alphabet. For example, if k - 3 then the letter a in plaintext becomes din ciphertext, B in plaintext becomes E in ciphertext, and the plaintext message "bob, i love you. Alice" becomes ere, loryh brx. Dolfh' in ciphertext Note that k may be negative. It means that you should substitute the letter in the plaintext message that is lk letters earlier. Write a program that prints out the Caesar cipher for the given input (described in Input Format). Note: Transform only English alphabet (case- preserving) and preserve other characters such as Arabic numerals or punctuation. INPUT AND OUTPUT EXAMPLE Input The input contains two lines. Both lines are followed by a newline character. The first line contains an integer fork(-10000
