Car Fleet

**Problem Statement:** Given the required input arguments, write an efficient algorithm to solve the **Car Fleet** problem. Implement the required logic as specified by standard definitions for this classic algorithmic challenge. **Hint / Expected Approach:** Sort by position, compute time-to-reach, stack merge **Edge Cases to Consider:** - (1) Single car - (2) All same speed - (3) Car behind faster but too far

Examples

Example 1
Input: 12, [10,8,0,5,3], [2,4,1,1,3]
Output: 3
Explanation: Classic
Example 2
Input: 10, [3], [3]
Output: 1
Explanation: Single car
Example 3
Input: 100, [0,2,4], [4,2,1]
Output: 1
Explanation: All merge

Constraints

  • ▪Input arguments are within valid ranges
  • ▪Optimize for execution speed
  • ▪Handle null/empty inputs gracefully

Watch Out For Edge Cases

  • ▪Single car
  • ▪All same speed
  • ▪Car behind faster but too far
