Possible to reach at the end of array of not(only forward move) /Jump Game

class Solution:
    def canJump(self, nums: List[int]) -> bool:
        max_reach=0

        for i in range(len(nums)):
            if i>max_reach: #This handles the situation when you came to i but using all the elements before i can't make you reach to i for eg.[3,2,1,0,4] so when nums[i]==0 then i came ahead of max_reach and using 3,2 and 1, you can't reach 0.
                return False
            max_reach=max(i+nums[i],max_reach)

        return True #When your max_reach can go till the last element or ahead of the last element, you can obvious reach the last element.
