Hello my amazing reader,
To help you work with the Greedy Algorithm Spotting Framework that we developed yesterday, here is a phenomenal question that can be solved very easily (and optimally) by implementing Greedy Algorithms. This solution is much easier than implementing the Dynamic Programming based solution.
This problem can be found as problem 55. Jump Game on Leetcode.
Problem
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.
Return true
if you can reach the last index, or false
otherwise.
Example 1:
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.
Example 2:
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.
