Solving Car Fleet in go. Please try yourself first to solve the problem and submit your implementation to LeetCode before looking into solution.

## Problem Description

A car can never pass another car ahead of it, but it can catch up to it, and drive bumper to bumper at the same speed.

The distance between these two cars is ignored - they are assumed to have the same position.

How many car fleets will arrive at the destination?

Example 1:

``````Input: target = 12, position = [10,8,0,5,3], speed = [2,4,1,1,3]
Output: 3
Explanation:
The cars starting at 10 and 8 become a fleet, meeting each other at 12.
The car starting at 0 doesn't catch up to any other car, so it is a fleet by itself.
The cars starting at 5 and 3 become a fleet, meeting each other at 6.
Note that no other cars meet these fleets before the destination, so the answer is 3.``````

Note:

1. `0 <= N <= 10 ^ 4`
2. `0 <= position[i] < target`
3. All initial positions are different.
