        { parsed: { amount: new BN(100) }, compressedAccount: { lamports: new BN(10) } },
        { parsed: { amount: new BN(50) }, compressedAccount: { lamports: new BN(5) } },
        { parsed: { amount: new BN(25) }, compressedAccount: { lamports: new BN(2) } },
      ];
      const transferAmount = new BN(75);
      const maxInputs = 2;

      const [selectedAccounts, total, totalLamports, maxPossibleAmount] =
