You are given a *0-indexed* array of integers ~nums~ of length ~n~. You are initially positioned at index 0.
Each element ~nums[i]~ represents the maximum length of a forward jump from index ~i~. In other words, if you are at index ~i~, you can jump to any index ~(i + j)~ where:
- ~0 <= j <= nums[i]~ and
- ~i + j < n~
Return /the minimum number of jumps to reach index /~n - 1~. The test cases are generated such that you can reach index ~n - 1~.
*Example 1:*
#+begin_src
Input: nums = [2,3,1,1,4]
Output: 2
Explanation: The minimum number of jumps to reach the last index is 2. Jump 1 step from index 0 to 1, then 3 steps to the last index.
#+end_src
*Example 2:*
#+begin_src
Input: nums = [2,3,0,1,4]
Output: 2
#+end_src
*Constraints:*
- ~1 <= nums.length <= 10^{4}~
- ~0 <= nums[i] <= 1000~
- It's guaranteed that you can reach ~nums[n - 1]~.
