Then he asks him to determine if there exists an element in the array such that the sum of the elements on its left is equal to the sum of the elements on its right. The game starts with an array of distinct integers and the rules are as follows: Bob always plays first and the two players move in alternating turns. In a single move, a player chooses the maximum element currently present in the array and removes it as well as all the other elements to its right. If you're standing in cell or the value of , you can walk or jump off the end of the array and win the game. In other words, you can move from index to index , , or as long as the destination index is a cell containing a . If the destination index is greater than , you win the game. The goal of this answer was to provide a solution that doesn't use extra space, I should have been clear in the answer itself. (Editing it). @Ekansh Well, I could be wrong but it seems to me the reversal of an array would have the effective time complexity of O(N), which the best you can get to rotate the array as there can not be a solution with O(1).
