Minimum Canvas Strokes

You are given an n (where n is a positive integer) representing the dimensions of a square canvas, i.e., an n × n canvas. Your task is to determine the minimum number of strokes required to paint the entire canvas. It turns out that the minimum number of strokes is exactly n. In other words, mathematically, the answer can be expressed as:

$$\text{min\_strokes}(n) = n$$

This problem may look trivial at first glance, but it serves as an introduction to input/output processing in programming contests.

inputFormat

The input consists of a single line containing one integer n (1 ≤ n ≤ 10⁴), which denotes the dimension of the canvas.

outputFormat

Output a single integer, which is the minimum number of strokes required to paint an n × n canvas.
