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.
true if you can reach the last index, or
Input: nums = [2,3,1,1,4] Output: true Explanation: Jump 1 step from index 0 to 1, then 3 steps to the last index.
Input: nums = [3,2,1,0,4] Output: false Explanation: 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.
1 <= nums.length <= 104
0 <= nums[i] <= 105
def canJump(self, nums: List[int]) -> bool:
max_jump = 0
n = len(nums)
for key, value in enumerate(nums):
if max_jump < key:
if max_jump >= n-1:
max_jump = max(key+value,max_jump)
