$s,t$ haqiqiy sonlar berilgan. Hisoblang: $h(s,t) + max(h(s - t,st),h(s-t,s + t)) + h(1,1)$ bu yerda


$$h(a,b) = \frac{a}{b^2 + 1} + \frac{b}{a^2 + 1} - (a - b) ^ 3$$


Kiruvchi ma`lumotlar: $s,t$-haqiqiy son ($1\le y \le 50$)


Chiquvchi ma`lumotlar: Masala yechimi $10^{-2}$ aniqlikda chiqarilsin
