Given the single character string str $$="\mathrm{d}$$ ". 1. Compute sha-256 value of str in Hex with no colons separating the hex values. 2. The sha-256 value of str forms a leaf node in a larger Merkle tree at index 3 . Given the merkle branch below associated with this leaf node calculate the Merkle root $$\begin{array}{l}\text{ 2e7d2c03a9507ae265ecf5b5356885a53393a2029d241394997265ala25aefc6 }\\ 62af5c3cb8da3e4f25061\text{ e829ebeea5c75 13c54949115b lacc225930a90154da }\\ \text{ d6cf2ad3f66d0599d97346c6aad0f1081913df26d8b80e4ffa052e0al f839 1c6 }\\ \text{ 2e15ecd6e7d77f95c9275a7cc4cf9338518ef7b9490097510f994d8111 ccf }1\mathrm{d}8\end{array}$$ 3. Write the root in the format used by Bitcoin proof of work.
