Right-Angled Triangle Area Calculation

Given two integers representing the base and height of a right-angled triangle, calculate the area using integer (floor) division. The area is computed using the formula: \(\lfloor\frac{\text{base} \times \text{height}}{2}\rfloor\). Note that the division here is integer division, which means the fractional part is discarded.

inputFormat

The input consists of a single line containing two space-separated integers: base and height.

outputFormat

Output a single integer representing the floor of the area of the right-angled triangle, computed as \(\lfloor\frac{\text{base} \times \text{height}}{2}\rfloor\).
