FlashLoan Arbitrage

This smart contract performs a flashloan arbitrage between Aave's USDC and DAI. It performs the following operations:

Deposit 1,000,000,000 USDC to a DEX contract (dexContractAddress) using the depositUSDC() function. Buy DAI from the DEX contract using the buyDAI() function. Deposit the DAI bought in the previous step to the DEX contract using the depositDAI() function. Sell the deposited DAI for USDC using the sellDAI() function. The smart contract repays the flashloan and keeps the profit if the arbitrage opportunity is profitable.
