Jump Game
Detailed guide and Python implementation for the 'Jump Game' problem.
Problem Statement
You are given an integer array nums. You are initially positioned at the array's first index, and each element in the array represents your maximum jump length at that position.
Return True if you can reach the last index, or False otherwise.
Write a function canJump(nums: List[int]) -> bool.
- •1 <= len(nums) <= 10^4
- •0 <= nums[i] <= 10^5
Examples
nums = [2,3,1,1,4]
True
Jump 1 step from index 0 to 1, then 3 steps to the last index.
nums = [3,2,1,0,4]
False
You will always arrive at index 3. Its maximum jump length is 0, which makes it impossible to reach the last index.

Edge Cases to Watch
- Empty input structures
