Greedy

Jump Game II (Min Jumps)

**Problem Statement:** Given the required input arguments, write an efficient algorithm to solve the **Jump Game II (Min Jumps)** problem. Implement the required logic as specified by standard definitions for this classic algorithmic challenge. **Hint / Expected Approach:** Greedy: expand range per level **Edge Cases to Consider:** - (1) Already at last index - (2) Single element - (3) All 1s array

Examples

Example 1
Input: [2,3,1,1,4]
Output: 2
Explanation: Jump 2→3→end
Example 2
Input: [2,3,0,1,4]
Output: 2
Explanation: Jump 2→3→end
Example 3
Input: [1]
Output: 0
Explanation: Already there

Constraints

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

Watch Out For Edge Cases

  • ▪Already at last index
  • ▪Single element
  • ▪All 1s array
