Problem - IPO

You have initial capital $W$ and can complete at most $k$ projects. Each project has a profit and a minimum capital required. After completing a project, your capital increases by its profit. Maximize final capital. For $k=2$, $W=0$, $profits=[1,2,3]$, $capital=[0,1,1]$, the answer is $4$. Do project $0$ (profit $1$, now have $1$), then project $2$ (profit $3$, now have $4$).

Here's a two-constraint greedy problem.

You need enough capital to start, then you want maximum profit.
