Jump Game Leetcode Solution – 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 trueif you can reach the last index, or falseotherwise.
i) For Input 1, we can jump 1 step from index 0 to 1, then 3 steps to the last index. ii) For Input 2, we can try different ways but every time we will arrive at index 3. Its maximum jump length is 0. So we can’t go further from that index. So it is impossible to reach the last index.
Let Nbe the length of the input array. Time complexity: O(N) We are only iterating over the input array. So it will take O(N)time. Space complexity: O(N) We are using only constant space. So the space complexity is O(1). Reference: https://en.wikipedia.org/wiki/Greedy_algorithm
