1. K-Radius Subarray Averages

Moderate

0/80

Asked in company

You are given a 0-indexed array of integers nums of length n and an integer k.

The k-radius average for a subarray of nums centered at index i is the average of all elements between indices i - k and i + k (inclusive). The average should be calculated using integer division, which truncates any fractional part.

However, if there are fewer than k elements before or after index i, the k-radius average is defined to be -1.

Your task is to build and return an array avgs of length n, where avgs[i] is the k-radius average for the subarray centered at index i.

2. Middle Of Linked List

Easy

80% success

0/40

Asked in companies

Given a singly linked list of 'N' nodes. The objective is to determine the middle node of a singly linked list. However, if the list has an even number of nodes, we return the second middle node.

Note:

1. If the list is empty, the function immediately returns None because there is no middle node to find.
2. If the list has only one node, then the only node in the list is trivially the middle node, and the function returns that node.
