Calculate Remaining Lives in (\text{Touhou: Oriental Red Magic}

)

The game "Oriental Red Magic" has six stages, namely \(\text{Stage 1}\) to \(\text{Stage 6}\). The protagonist starts with 2 lives. In addition, the following bonuses are awarded:

• When the score reaches (i.e., is greater than or equal to) \(10^7\), \(2 \times 10^7\), \(4 \times 10^7\), and \(6 \times 10^7\) points, the protagonist receives one extra life for each milestone reached.
• Upon clearing \(\text{Stage 3}\) and \(\text{Stage 5}\), an additional life is rewarded.

You are given that the protagonist has just cleared \(\text{Stage }x\) and currently has a score \(s\). Determine the total number of lives the protagonist now has.
