STEP 1 => Deployed the Token contracts for TokenA and TokenB and copied its address to deploy the SimpleDEX contract.
STEP 2 =>
Deploying SimpleDEX.sol with Contract address of TokenA and TokenB with exchange rate 5.
STEP 3 =>
Approving and transferring the tokens to SimpleDEX contract.
STEP 4 =>
Interacting with SimpleDEX.sol and intiating exchangeTokenAForTokenB function with 500 amount of token.
STEP 5 =>
Verifying the updated balance of TokenA and TokenB , Here TokenA has 10500 after exchange TokenB has 7500 after exchange as exchange rate was 5 hence 5*500 = 2500 deducted. Updated Balances can be verified under balanceOf function of both tokens.
