This is a cryptography question from the book Introduction to Modern Cryptography

Show that for any CPA-secure public-key encryption scheme for single-bit messages, the length of the ciphertext must be super logarithmic in the security parameter. Hint: Sup pose that the length of a ciphertext was Ice klog n for some constant k. What is the size of the ciphertext space C?
