LESSON 292 OF 410 · MEMOIZATION

Jump Game II - O(n^2) Time Complexity with Memoization in Python

Practice O(n2) - Memoization

Given an array of non-negative integers, you are initially positioned at the first index of the array.

Each element in the array represents your maximum jump length at that position.

Your goal is to reach the last index in the minimum number of jumps.

Example:

Input: [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.
			

Note:

Apply memoization to the previous solution. Your algorithm should run in O(n^2) time and use O(n) extra space.
