# Bank Account

**Computer Science**Level 3

Alice has 100 dollars in her bank account, and she wants to withdraw *at least* 10 dollars in the course of 7 days. However, the bank has a weird policy. On the \(i^\text{th}\) day, she will be paid \(p_i\) dollar if she doesn't withdraw any money. If she wants to withdraw, she can only withdraw *exactly* \(q_i\) dollars.

The table below describes \(p\) and \(q\) on the \(i^\text{th}\) day:

i | 1 | 2 | 3 | 4 | 5 | 6 | 7 |

p | 5 | 4 | 8 | 4 | 9 | 6 | 3 |

q | 4 | 9 | 5 | 2 | 5 | 2 | 6 |

Assume that Alice cannot deposit any money, what is the maximum amount of money can Alice has in her bank account after 7 days?
