Jump Game II

Explore how to solve the Jump Game II problem by determining the minimum number of jumps needed to reach the last position. Learn to apply greedy techniques for optimization, develop a clear understanding of problem constraints, and implement an O(n) time and O(1) space complexity solution.

We'll cover the following...

Statement

In a single player jump game, the player starts at one end of a series of squares and aims to reach the last square.

At each turn, the player can take up to ss steps toward the last square, where ss is the value of the current square.
