Summary

The playersHand function incorrectly treats a card value of 0 as 10, which is not in line with standard blackjack rules.

Vulnerability Details

In the playersHand function, the condition if (cardValue == 0 || cardValue >= 10) incorrectly maps 0 to a value of 10. This misinterpretation can lead to incorrect hand value calculations for the player.

Impact

This incorrect calculation may lead to an unfair game, as the player's hand value would be artificially inflated, potentially altering the game outcome.
