Challenge Problems
Push your limits with challenges.
Question 1
If the letters E, T, A, O, N are to be encoded with frequencies E=0.12, T=0.09, A=0.08, O=0.07, and N=0.06, derive optimal Huffman codes for them.
💡 Hint: Construct the tree using the least frequent letters first.
Question 2
If Morse code were to include a new symbol 'S' represented by '--', how would this affect the current codes for E, T, and A if we start decoding from the beginning?
💡 Hint: Think of how the new code interacts with existing symbols.
