Problem C
Budget

You are a member of the newly formed Mars colonization effort. Your job is to budget for three projects: the cloud seeding project, the equatorial magnetizer, and the space elevator. Given a budget, and the cost of the three projects, determine if all projects can be started immediately.

Input

Input consists of four lines.
The first line consists of one integer $b$, the budget. $-10^6 \leq b \leq 10^6$
The second line consists of one integer $p_1$, the cost of the cloud seeding project. $-10^6 \leq p_1 \leq 10^6$
The third line consists of one integer $p_2$, the cost of the equatorial magnetizer project. $-10^6 \leq p_2 \leq 10^6$
The fourth line consists of one integer $p_3$, the cost of space elevator project. $-10^6 \leq p_3 \leq 10^6$

Output

If all projects can be started immediately, print Budget is sufficient., else print Budget is insufficient.
