Jump Game
Updated Jan 31, 2026
Problem
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.
Constraints
1 <= nums.length <= 10^4
0 <= nums[i] <= 10^5
Examples
Example 1
Input:
nums = [2,3,1,1,4]
Output:
true
Jump 1 step from index 0 to 1, then 3 steps to the last index.
Example 2
Input:
nums = [3,2,1,0,4]
Output:
false
You will always arrive at index 3 no matter what. Its maximum jump length is 0, which makes it impossible to reach the last index.
Function Signature
def canJump(self, nums: list[int]) -> bool
How to Submit
Implement a Solution class with a canJump method.
Your method will be called with the input parameters and should return the answer.
