Round duration - 60 minutes
Round difficulty - Medium

Round 1  was a coding round of 60 min which started around 5:30PM in which 2 problem statements were given. The questions were based on Array and linked list. The platform used for test was coding which was user friendly and which use to display number of test cases passed and some test cases were hidden.

Q1. 
Problem: Deletion in Circular Linked List
You are provided with a Circular Linked List of integers and a specific integer, referred to as 'key'.
Your task is to implement a function that locates the spec...read more
Ans. Recursion
The idea is to use a recursive approach to find the given key and then remove that node. The recursive idea is very clear that we will traverse through the circular linked list, and we will check if the value of the node is equal to the given key. 
 
We will define a function deleteNodeHelper(root, key, head) to remove the key in which the head is the starting node of the linked list, and we will send ...read more

Q2. 
Rearrange Array: Move Negative Numbers to the Beginning
Given an array ARR consisting of N integers, rearrange the elements such that all negative numbers are located before all positive numbers. The orde...read more
Ans. Using Sorting
Approach: A brute force approach could be to just sort the given array in ascending order. This will result in all negative numbers to appear at the beginning and positive number at the end.
Space Complexity: O(1)Explanation:
O(1)
 
Because no extra space is required.
Time Complexity: O(nlogn)Explanation:
O(N*logN), where N is the number of elements in the array.
 
In the worst case, sorting requires O...read more
