$66,65,68,67,70,70,71,70,72,71,70,70,71,72$

In a standard uncompressed representation, each digit would likely be represented with $4$ bits $(6$ as $0110,8$ as $1000,$ etc$).$

The Huffman coding compression algorithm reduces the amount of bits required to represent data by using shorter bit codes to represent the most common source symbols.

If they apply Huffman coding to the temperature data, which digit is the most likely to be represented with a shorter bit code?
