A bike route has checkpoints numbered from a to b, both included. Every checkpoint whose number is a multiple of k gets a water station. Zero is a multiple of every number.
Count the water stations.
**Constraints:** -1000 <= a <= b <= 1000 and 1 <= k <= 1000.
Input. One line with three integers a, b and k.
Output. One integer: the number of checkpoints whose number is a multiple of k.
Example 1 input
```
1 10 3
```
Output
```

Example 2 input
```
-5 5 2
```
Output
```
