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 this tutorial, we’ll discuss the two-pointer approach for solving problems involving arrays and lists. This technique is an easy and efficient way to improve the performance of our algorithm. 2. Technique Description In many problems involving arrays or lists, we have to analyze each ...
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...
Assume that you are given a task to find a pair in an array that sums to S. Whenever I encounter problems around this line, the first approach that I can think of is theTwo-pointer approach. The reason behind that is it's super easy to understand and implement. How sorted array work?
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...
🎭 PsuendoCode Union Find Algorithm Pattern ♾ ⏰: O(V * logV) 🪐: O function find(int[] parent, i) { if (parent[i] == -1) return i; return find(parent, parent[i]); function union(int[] parent, x, y) { xset = find(parent, x); yset = find(parent, y); parent...
Two Pointer Algorithm to Summary the Ranges Since the array is already sorted, we can start scanning from left to the right, then continuously jump the pointer to the furthest if the next numbers are the neighbors. We then can generate the ranges for two cases: the single value (disjoint)...

V503. Nonsensical comparison: pointer < 0. V504. Semicolon ';' is probably missing after the 'return' keyword. V505. The 'alloca' function is used inside the loop. This can quickly overflow stack. V506. Pointer to local variable 'X' is stored outside the scope of this variable. ...
