PythonServer Side ProgrammingProgramming

Suppose we have a list of numbers called nums where each number shows the maximum number of jumps we can make; we have to check whether we can reach to the last index starting at index 0 or not.

So, if the input is like nums = [2,5,0,2,0], then the output will be True, as we can jump from index 0 to 1, then jump from index 1 to end.

To solve this, we will follow these steps−

• n := size of nums

• arr := an array of size n and fill with false

• arr[n - 1] := True

• for i in range n - 2 to 0, decrease by 1, do

• arr[i] := true if any one of arr[from index i + 1 to i + nums[i]] is true

• return arr

Let us see the following implementation to get better understanding −

## Example

Live Demo

```class Solution:
def solve(self, nums):
n = len(nums)
arr = [False] * n
arr[n - 1] = True
for i in range(n - 2, -1, -1):
arr[i] = any(arr[i + 1 : i + nums[i] + 1])
return arr
ob = Solution()
nums = [2,5,0,2,0]
print(ob.solve(nums))```

## Input

`[2,5,0,2,0]`

`True`
