I applied via Campus Placement and was interviewed in Nov 2021. There were 4 interview rounds.
Binary search has O(log n) time complexity for arrays and O(n) for linked lists.
Binary search is efficient for arrays due to their random access nature.
Linked lists require sequential traversal, making binary search inefficient.
For arrays, the time complexity is O(log n) as the search space is halved with each iteration.
For linked lists, the time complexity is O(n) as all nodes must be visited to find the target.
Binary...
Construct a tree using inorder and postorder traversal lists.
The last element of the postorder list is the root of the tree.
Find the root in the inorder list and split the list into left and right subtrees.
Recursively construct the left and right subtrees using the corresponding sublists.
Return the root node.
Time complexity: O(n^2) in worst case, O(nlogn) on average.
Find depth of binary tree through recursion and iteration
Recursively traverse left and right subtrees and return the maximum depth
Iteratively traverse the tree using a stack or queue and keep track of the depth
Depth of an empty tree is 0
Depth of a tree with only one node is 1
Intersection of two arrays is the common elements present in both arrays.
Sort both arrays and use two pointers to compare elements.
Use a hash set to store elements of one array and check for presence in the other array.
If arrays are already sorted, use binary search to find common elements.
Find the heavier ball from 8 identical balls using a balance weighting machine in least number of tries.
Divide the balls into 3 groups of 3, 3, and 2 balls.
Weigh the first two groups against each other.
If they balance, the heavier ball is in the remaining group of 2 balls.
If one group is heavier, weigh two balls from that group against each other.
If they balance, the heavier ball is the remaining ball.
If one ball is he

Find the longest substring without repeating characters
Use a sliding window approach to keep track of the current substring
Use a hash set to store the characters in the current substring
Update the start index of the window when a repeating character is encountered

To form a binary tree, create nodes with left and right child pointers.
Start by creating a root node.
For each node, create left and right child nodes.
Repeat the process until all nodes are created.
Design a map
Consider the purpose of the map (e.g., navigation, data visualization)
Decide on the level of detail and scale of the map
Choose appropriate symbols and colors for different features
Include a legend or key to explain the map symbols
Ensure the map is easy to read and understand
