Floor Division Calculation

In class, students often practice mental arithmetic. In this exercise, you are given two integers (x) and (y) and are asked to compute ( \lfloor \frac{x}{y} \rfloor ), where ( \lfloor a \rfloor ) represents the greatest integer less than or equal to (a). For example, (\lfloor 1.1 \rfloor=1), (\lfloor 4 \rfloor=4), and (\lfloor -2.2 \rfloor=-3).

Note: In languages such as C++, if you directly divide two integers using the expression x / y, the result is truncated towards zero. Therefore, you must ensure your solution correctly returns the value of (\lfloor \frac{x}{y} \rfloor), i.e. rounding down to the nearest integer.

inputFormat

The input consists of a single line with two space-separated integers (x) and (y). You may assume that (y \neq 0).

outputFormat

Output a single integer, the value of ( \lfloor \frac{x}{y} \rfloor ).
