We will set up a Post Confirmation lambda trigger for adding new users automatically to a certain group. in this guide, we will implement the code for the said function, assign permissions and attach the Lambda function to the Cognito user pool.
You are given the heads of two sorted linked lists, list1 and list2. Merge the two lists into one sorted list. The list should be made by splicing together the nodes of the first two lists. Return the head of the merged linked list.
Design and implementation of a special kind of stack called a MinStack. The MinStack supports the usual stack operations such as push, pop, and top, but it also provides a method to retrieve the minimum element in constant time, O(1).
You are keeping the scores for a baseball game with a unique set of rules. At the beginning of the game, you start with an empty record. You're given a list of strings operations, where each element represents an operation to apply to the record.
You are given an integer array nums of length n. The task is to create a new array ans of length 2n such that ans[i] == nums[i] and ans[i + n] == nums[i] for 0 <= i < n (0-indexed). In simpler terms, the array ans is formed by concatenating two copies of the array nums.
The problem at hand is to remove duplicates from a sorted integer array nums in-place, such that each unique element appears only once. Additionally, we need to return the number of unique elements present in the modified array.
You are given two integer arrays nums1 and nums2, sorted in non-decreasing order, and two integers m and n, representing the number of elements in nums1 and nums2 respectively. Merge nums1 and nums2 into a single array sorted in non-decreasing order.
In this article, we cover various techniques for handling process environment variables in TypeScript, such as using type assertions, creating typed configuration objects, using type guards, and leveraging configuration libraries like dotenv and dotenv-safe.
This error occurs when you have not explicitly given a type to a value. Resulting in the implicit assignment of the type "never" to the value. The "never" type always expects the value to the empty and throws an error when its not empty.
This error occurs when you are not passing all the required props or only passing some of the required props to the component. Pass all the props or define the typing of the component accordingly to handle this error.
