generate.js
- Enter its odd numbers' sum in
scripts/deploy.ts
4. Deploy solution contract
npx hardhat run scripts/deploy.ts --network optimism
Enter the deployed contract's address in test/Test.ts
5. Generate puzzle solution
node generate.js
Once you have it, enter the puzzle solution in test/Test.ts
