design a ADT to implement push(), pop() method as stack, and also has a getMinElement(). Require that getMinElement() is constant time but push()/pop() do not have to be constant time at first. Then for improvement, these three methods are all required to be constant time
A boy goes to his grandmother’s house. There he either does yoga in the morning / plays tennis in the evening / does neither. However he does not do both on the same day. We know that 22 days he did either 1 activity. 24 mornings he did nothing. 12 evenings he did nothing. How many min days did he stay there to have done this?
1) Given a array and a sum, find all the pairs in the array which have the given sum. 2) Given a BST you need to identify swapped nodes
If you have all the numbers from 1 to 1'000,000, except one of them. How would you find out which number is missing?
You have a long set of numbers. More than 400k. How would you search if a specific number is in set? They expect a better solution than looping the set until you find the number.
Given two binary trees T1 and T2. Find if T2 is a sub-tree of T1.
Make a program that writes a Binary Search Tree to a file. Now create a program that reads those files and recreates a Binary Search Tree.
You are given an array of numbers. You need to print the length of the maximum continuous sequence that you encounter. For example if input is [3,8,10,1,9,6,5,7,2 ], the continuous sequences are{1,2,3} and {5,6,7,8,9,10} the latter is the longest one so the answer becomes 6. O(n) solution was asked for, assuming you have a hash map which supports O(1) insertion and fetching operations
