Jump Game II
Detailed guide and Python implementation for the 'Jump Game II' problem.
Problem Statement
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]. The test cases are generated such that you can reach the last index.
Write a function jump(nums: List[int]) -> int.
- •1 <= len(nums) <= 10^4
- •0 <= nums[i] <= 1000
Examples
nums = [2,3,1,1,4]
2
Jump 1 step from index 0 to 1, then 3 steps to the last index.
nums = [2,3,0,1,4]
2
Jump 1 step from index 0 to 1, then 3 steps to the last index.
