P1464 Function

For a recursive function $w(a,b,c)$: - If $a \le 0$ or $b \le 0$ or $c \le 0$, return $1$. - If $a>20$ or $b>20$ or $c>20$, return $w(20,20,20)$. - If $a

Multiple lines of input. Each line contains three integers $a, b, c$. The input ends with $-1,-1,-1$.

Output multiple lines. Each line should be in the format: `w(a, b, c) = ans` Mind the spaces.

### Constraints - Each input number is an integer in $[-9223372036854775808, 9223372036854775807]$. - The number of input lines excluding $-1, -1, -1$, denoted $T$, satisfies $1 \leq T \leq 10^5$. Translated by ChatGPT 5
