* The remaining scripts should be organized into the leaves of a binary tree. This can be a balanced tree if each of the conditions these scripts correspond to are equally likely. If probabilities for each condition are known, consider constructing the tree as a Huffman tree.
'''Computing the output script''' Once the spending conditions are split into an internal key <code>internal_pubkey</code> and a binary tree whose leaves are (leaf_version, script) tuples, the output script can be computed using the Python3 algorithms below. These algorithms take advantage of helper functions from the [bip-0340/referency.py BIP340 reference code] for integer conversion, point multiplication, and tagged hashes.

These algorithms take advantage of helper functions from the [[bip-0340/reference.py|BIP340 reference code]] for integer conversion, point multiplication, and tagged hashes.
First, we define <code>taproot_tweak_pubkey</code> for 32-byte [[bip-0340.mediawiki|BIP340]] public key arrays.
The function returns a bit indicating the tweaked public key's Y coordinate as well as the public key byte array.
