Tekislikda kesmaning uchlari berilgan: $A(x_{1}; y_{1})$ va $B(x_{2}; y_{2})$. Kesma o'rtasi $M(x_{M}; y_{M})$ ning koordinatalarini toping:
$$x_{M} = \frac{x_{1} + x_{2}}{2}, \qquad y_{M} = \frac{y_{1} + y_{2}}{2}$$
Kiruvchi ma'lumotlar
Bitta qatorda to'rtta butun son: $x_{1}$, $y_{1}$, $x_{2}$ va $y_{2}$.
Chiquvchi ma'lumotlar
Bitta qatorda ikkita son: $x_{M}$ va $y_{M}$, har biri nuqtadan keyin aynan 1 ta raqam bilan (masalan, 2.0). Yaxlitlangan natija nol bo'lsa (masalan, $-0.01$), u 0.0 ko'rinishida chiqariladi (-0.0 emas).
Izoh
$-10^{4} \le x_{1}, y_{1}, x_{2}, y_{2} \le 10^{4}$
