Root Cause

Some internal functions, such as addCardForDealer and initializeDeck, are only called once in the contract:

Impact

Having internal functions that are called only once adds unnecessary function call overhead, slightly increasing gas consumption and adding complexity to the contract's structure.

Recommendations

• Inline Single-Use Functions: Incorporate the logic of these functions directly into the place where they are called to optimize gas usage and simplify the code.

• Code Clarity: Ensure that inlining the functions does not negatively impact the readability of the code.
