Jump Game II: Minimum Leaps Greedy BFS

Targeted in FAANG & Tech OA:AmazonGoogle
Real-World Engineering Context
Used in network packet hop minimization, wireless mesh relay optimization, and game engine character navigation pathfinding.
You are given a 0-indexed array of integers `nums` of length `n`. You are initially positioned at `nums[0]`. Each element `nums[i]` represents the maximum length of a forward jump from index `i`. Return the minimum number of jumps to reach `nums[n - 1]`. You can assume that you can always reach the last index.

Sample Test Cases

Input: [[2,3,1,1,4]]
Expected: 2
Input: [[2,3,0,1,4]]
Expected: 2
Input: [[0]]
Expected: 0

Constraints

  • 1 <= nums.length <= 10^4
  • 0 <= nums[i] <= 1000
  • It's guaranteed that you can reach nums[n - 1].
