Hint! Robert Sedgewick

To be honest, this challenge was pretty simple. I decrypted the text using online Vigenere cipher decrypter, which is the first cipher I try in suchcases, just after Caesar cipher.

The key was “pragyan” and the result was: “a game. a movie star. his wife. name of the cs textbook. the winner takes it all.”

I then used the hint about Robert Sedgewick, which is a famous computer science professor at Princeton University. I found that the flag is his CS textbook title.

The flag was pragyanctf{algorithms}.
