### Question:
NwpTool extends BasicTool { static int calculateStride(int n, int nwpN) { int stride; if (nwpN > 1) { stride = (n - 1) / (nwpN - 1); } else { stride = 1; } return stride; } NwpTool(); static void main(String[] args); @Override void initialize();  }### Answer:
@Test public void testCalculateStride() { assertEquals(1, NwpTool.calculateStride(108, 0)); assertEquals(1, NwpTool.calculateStride(108, 1)); assertEquals(107, NwpTool.calculateStride(108, 2)); assertEquals(53, NwpTool.calculateStride(108, 3)); assertEquals(200, NwpTool.calculateStride(201, 2)); assertEquals(149, NwpTool.calculateStride(300, 3)); }
