In this homework, you will modify the transfer amount in out existing logic. Currently it is transferring all the balance source account holds. Instead let's change this to a defined amount.
Step 1

Step 2
Run cargo test to make sure project is still working
Optional
Instead of hard coding the amount, you can get the amount as input from the user and then transfer that amount of tokens.
