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) ...
We'll start with initializing our two pointers, let's name them 'low' and 'high'. low: this pointer will point to the index of the smallest element, in a sorted array it will be the first element of the array. high: this pointer will point to the index of the greatest element, in...
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...
Let us do discuss the working of two pointer algorithm in brief which is as follows. The algorithm basically uses the fact that the input array is sorted. We start the sum of extreme values (smallest and largest) and conditionally move both pointers. We move left pointer ‘i’ when the ...
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 ...
This paper presents a two-pointer detection strategy to find detachable subassemblies very quickly. A summation operator and a list with two pointers are used to check the interferences between components in a minimum number of steps. Then, a ternary bees algorithm is proposed to identify new ...
If we think similarly as we solved in the two sum problem, what we need to sort the arrays. We started from the beginning of one array and the end of another array. That was our two-pointer algorithm where we traversed the pointers based on the sum of the current ...
