high = len(arr) - 1 # as python follows 0-indexing Step 2. Check elements at both pointers At each step, we will check if the elements at both pointers are equal to the target or satisfy the condition or not. There are 3 possible outcomes: result = arr[low] + arr[high] 2.1 resu...

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 ...
Program to compare two strings using pointers in C#include <stdio.h> //Macro for maximum number of characters in a string #define MAX 100 int main() { //declare string variables char str1[MAX] = { 0 }; char str2[MAX] = { 0 }; int loop; //loop counter int flag = 1; //...
The idea is to use a sorted array to save the values of the nodes in the BST by using an inorder traversal. Then, we use two pointers which begins from the start and end of the array to find if there is a sum k. Time Complexity: O(n), Space Complexity: O(n). ...
双指针分为「对撞指针」、「快慢指针」、「分离双指针」。 参考来源:https://algo.itcharge.cn/ 对撞指针:两个指针方向相反。适合解决查找有序数组中满足某些约束条件的一组元素问题、字符串反转问题。 快慢指针:两个指针方向相同。适合解决数组中的移动、删除元素问题,或者链表中的判断是否有环、长度问题。
What ifnums1's size is small compared tonums2's size? Which algorithm is better? What if elements ofnums2are stored on disk, and the memory is limited such that you cannot load all elements into the memory at once? 这道题是之前那道Intersection of Two Arrays的拓展,不同之处在于这道题...

Using Pointers Method 1: Naive Approach (using loops) In this approach, we will compare the two strings using loops. advertisement Algorithm to compare two strings using loops: Step 1: Start the Program. Step 2: Input both the Strings. ...
Algorithm Step 1? Define the size of the rows and columns. Step 2? Create a function. Step 3? In this function create an empty matrix to store result of same number of rows and columns. Step 4? Run nested for loop to iterate through each element of both matrices. ...
