- Q1. Given two “ids” and a function getFriends(id) to get the list of friends of that person id, write a function that returns the list of mutual friends
- Ans.
Function to return mutual friends given two ids and getFriends(id) function
Call getFriends(id) for both ids to get their respective friend lists
Iterate through both lists and compare to find mutual friends
Return the list of mutual friends
- Q2. Given an “id” and a function getFriends(id) to get the list of friends of that person id, write a function that returns the list of “friends of friends” in the order of decreasing number of mutual friends,...
- Ans.
Function to return list of friends of friends in decreasing order of mutual friends
Use a set to store all friends of friends
Iterate through the list of friends of the given id
For each friend, iterate through their list of friends and count mutual friends
Sort the set of friends of friends by decreasing number of mutual friends
- Q3. Given a number of time slots – start time and end time,“a b”, find any specific time with the maximum number of overlapping. After solving the problem I had to prove my solution
- Ans.
Given time slots, find a specific time with maximum overlap. Prove solution.
Create a list of all start and end times
Sort the list in ascending order
Iterate through the list and keep track of the number of overlaps at each time
Return the time with the maximum number of overlaps
Prove solution by testing with different input sizes and edge cases
- Q4. Given an array of Integers, find the Longest sub-array whose elements are in Increasing Order
- Ans.
Find the longest sub-array with increasing order of integers.
Iterate through the array and keep track of the current sub-array's start and end indices.
Update the start index whenever the current element is smaller than the previous element.
Update the end index whenever the current element is greater than or equal to the next element.
Calculate the length of the sub-array and compare it with the longest sub-array found s
- Q5. Given an array of Integers, find the length of Longest Increasing Subsequence and print the sequence.
- Ans.
Find the length of longest increasing subsequence and print the sequence from an array of integers.
Use dynamic programming to solve the problem
Create an array to store the length of longest increasing subsequence ending at each index
Traverse the array and update the length of longest increasing subsequence for each index
Print the sequence by backtracking from the index with the maximum length
Time complexity: O(n^2)

- Q6. Given a Sorted Array which has been rotated, write the code to find a given Integer
- Ans.
Code to find a given integer in a rotated sorted array.
Use binary search to find the pivot point where the array is rotated.
Divide the array into two subarrays and perform binary search on the appropriate subarray.
Handle edge cases such as the target integer not being present in the array.
- Q7. You have a number of incoming Integers, all of which cannot be stored into memory. We need to print largest K numbers at the end of input
- Ans.
Use a min-heap to keep track of the largest K numbers seen so far.
Create a min-heap of size K.
For each incoming integer, add it to the heap if it's larger than the smallest element in the heap.
If the heap size exceeds K, remove the smallest element.
At the end, the heap will contain the largest K numbers in the input.
- Q8. Implement LRU Cache
- Ans.
LRU Cache is a data structure that stores the most recently used items and discards the least recently used items.
Use a doubly linked list to keep track of the order of items in the cache
Use a hash map to store the key-value pairs for fast access
When an item is accessed, move it to the front of the linked list
When the cache is full, remove the least recently used item from the back of the linked list and the hash map
Interview Preparation Tips
Experience: Facebook visited our campus in July, 2012. We had an online coding round hosted on InterviewStreet. We were asked to solve just one problem. The given problem boils down to : Given a undirected graph, source and destination, write the code to find the total number of distinct nodes visited, considering all possible paths.
Tips: Those shortlisted had to fly to Delhi for a Personal Interview. There were four rounds of interview, each of 45 minutes. The questions were simple. But just solving the given problem wasn't enough.
There was much more interaction and short questions asked related to the problem
Round: Technical Interview
Experience: The above mentioned questions wer asked in the interview. For every solution I was asked to write the code on paper. The code should also include the implementation of the data structures used (I used heaps - so I was asked to implement heaps ). They are looking for someone with good problem solving skills and conceptually sound in data structures
