Concurrency is the ability of multiple tasks to run simultaneously, while inheritance is a mechanism in object-oriented programming where a class inherits properties and behaviors from another class.
Concurrency allows multiple tasks to be executed at the same time, improving performance and efficiency.
Inheritance allows a new class to inherit properties and behaviors from an existing class, promoting code reusability.

Collection in Java is a framework that provides interfaces and classes to store and manipulate groups of objects.
Collections can be used to store objects of any type.
Some common collection types include ArrayList, LinkedList, HashSet, and TreeMap.
Collections can be sorted, searched, and filtered using various methods.
Iterators can be used to traverse through collections and perform operations on each element.

I applied via Recruitment Consultant and was interviewed before Nov 2020. There was 1 interview round.
Find an odd occurring number among even occurring numbers.
Use XOR operation to cancel out even occurring numbers and get the odd occurring number.
Iterate through the array and XOR each element with the result variable.
The final result will be the odd occurring number.
Print the spiral order of a binary tree and matrix.
For binary tree, use level order traversal and alternate direction for each level.
For matrix, use four pointers to traverse in spiral order.
Example for binary tree: 1 -> 2 -> 3 -> 4 -> 5 -> 6 -> 7 -> 8 -> 9
Example for matrix: 1 2 3 4 -> 8 7 6 5 -> 9 10 11 12 -> 16 15 14 13
Finding pairs in an array with a given sum.
Iterate through the array and for each element, check if the difference between the given sum and the element exists in the array.
Use a hash table to store the elements of the array and their indices for faster lookup.
If there are multiple pairs with the same sum, return any one of them.
If no pair is found, return null or an empty array.
Find total number of k element with given avg in an array in minimum time complexity.
Use sliding window technique to traverse the array in O(n) time complexity.
Maintain a sum variable to keep track of the sum of elements in the window.
If the sum of elements in the window is equal to k times the given avg, increment the count.
Move the window by subtracting the first element and adding the next element in the array.
Printing non-boundary elements of a binary tree
Traverse the tree in any order (preorder, inorder, postorder)
Check if the current node is not a boundary node (not the first or last node in its level)
If it is not a boundary node, print its value
Recursively traverse its left and right subtrees
