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
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
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
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
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)

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.
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.
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
Solution to performing operations on a large array of bits.
Use bitwise operators to perform operations on individual bits
Use a loop to iterate through the array and perform the operations
Ensure that the array is large enough to accommodate all the bits
Consider using a data structure like a bitset for efficient bit manipulation

In first round they asked me 2 coding questions where he asked me to code as close as possible to the actual one.
Ninja is tasked with merging two given sorted integer arrays ARR1
and ARR2
of sizes 'M' and 'N', respectively, such that the merged result is a single sorted array w...
Merge two sorted arrays into one sorted array in place.
Use two pointers to compare elements from both arrays and place them in the correct position in ARR1.
Start from the end of ARR1 and compare elements from both arrays, placing the larger element at the end of ARR1.
Continue this process until all elements from ARR2 are merged into ARR1.
Given a document represented as an array/list ARR
of words with length N
, find the smallest distance between two given words for multiple queries. The distance is defined as the ...
Find the smallest distance between two words in a document for multiple queries.
Iterate through the document array to find the indices of the two words in each query.
Calculate the absolute difference between the indices to get the distance.
If a word from the query is not present in the document, return the length of the document array.
Repeat the process for each query and output the smallest distance for each.

Then in the second round they asked a little about tree and told me to code 2 codes.
Given a binary tree of integers, return the level order traversal of the binary tree.
The first line contains an integer 'T', representing the number of te...
The problem requires implementing a function to return the level order traversal of a binary tree.
Implement a function that takes the root of the binary tree as input and returns the level order traversal of the tree.
Use a queue data structure to perform level order traversal.
Process each level of the tree one by one, starting from the root node.
Print the node values at each level in the order they appear from left to ...
Given an array of distinct positive integers ARR
and a non-negative integer 'B', find all unique combinations in the array where the sum is equal to 'B'. Numbers can be c...
Find all unique combinations in an array where the sum is equal to a given target sum, with elements in non-decreasing order.
Use backtracking to generate all possible combinations.
Sort the array to ensure elements are in non-decreasing order.
Track the current combination and sum while backtracking.
Terminate recursion when the sum equals the target sum.
Avoid duplicates by skipping elements that have been used in previou
