One pointer is incremented by one while the other is incremented by two. When the fast pointer reaches the end, the slow pointer will be at the middle of the linked list. The time complexity of this solution is O(n), and space complexity is O(1). 6. Conclusion In this ...
BY THIS ALGORITHM WE CAN SOLVE SUCH TYPE OF PROBLEMS IN LESS TIME COMPLEXICITY AS WELL AS IN EASY WAY; FOR EACH BEGINNER ONE SHOULD N KNOW ABOUT THIS ALGORITHM include using namespace std; // Two pointer technique based solution to find // if there is a pair in A[0..N-1] with a...
In the world of algorithm design and problem-solving, the two-pointer technique stands out as a powerful and widely utilized strategy. With its application extending to arrays, linked lists, and strings, this approach has proven its efficacy in reducing time complexity and, in certain cases...
and move the corresponding pointer. Nevertheless, we mustn’t forget about the case when either or reaches the end of their arrays. In this case, we must store the value from the other array and move its pointer. Finally, we return the resulting array . The complexity of the two-pointers...
In this case, thought our time complexity will be O(n) we will have additional space complexity of O(n) and extra stack space for the recursion while doing the inorder and reverse inorder traversal. Another way without storing the traversal, rather implementing the two-...
This problem reduces to one-dimensional case: in integer array, for each element you want to find element that is lower than current on the left and right sides. For every element you keep left and right positions for the element which is less than this element. (initially set to itselft...

Both pointers are initialized to point to head of A and B respectively, and the pointer that has the larger finding intersection of two sorted arrays. The best solution, but non-trivial, O(lg m + lg n): Although the above solution is an improvement both in run time and space complexity...

Space complexity :O(n). The size of thesetset can grow uptonn in the worst case. Approach #3 Using BST [Accepted] Algorithm In this approach, we make use of the fact that the given tree is a Binary Search Tree. Now, we know that the inorder traversal of a BST gives the nodes ...
