Can You Reach the Last Index?
Problem Description
You are given an array nums of non-negative integers. You begin at the first index, 0.
From any current index i, you are allowed to jump to any subsequent index j such that i < j <= i + nums[i].
Your task is to determine if it is possible to reach the last index of the array through a sequence of valid jumps.
Deliverables
Return true if the last index is reachable, and false otherwise.
Additionally, you must explain your chosen approach and analyze its time complexity.
Example
- Input:
nums = [2, 3, 1, 0, 4] - Output:
true
