Description
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.
Examples
Input:
nums = [2,3,1,1,4]Output:
trueExplanation:
Jump 1 step from index 0 to 1, then 3 steps to the last index.
Input:
nums = [3,2,1,0,4]Output:
falseExplanation:
The reachable range never reaches the last index, so the answer is false.
Input:
nums = [0]Output:
trueExplanation:
The array has only one element, so the starting position (index 0) is already the last index. No jumps are needed.
Constraints
- •
1 ≤ nums.length ≤ 10⁴ - •
0 ≤ nums[i] ≤ 10⁵
