Debugging section consists of basic algorithm and data structures while analytical sections consists of analogy based questions.
how many zeros are there in 100!
Given a binary tree, how would you set the keys/values of all the nodes and their child pointers to null. No language restriction. Do it iteratively in O(N) time with O(1) space complexity where N is the number of nodes in the tree. Other Details: - Tree is just a regular Binary Tree and doesn't have the BST property. - It is not guaranteed to be balanced. - You may do whatever you want to the tree however, you must ensure that all the nodes in the tree and their left/right pointers are set to null.
1) 6 hours problem - Walls and Guards, use triple loop as a solutions and matrix. 2) Live coding question - 3 boxes with apples, oranges and apple and oranges, famous problem.
Create a data structure that minimizes time complexity of retrieving median and inserting new element. Getting median should be O(1) and insertion should be O(log(n)).
Write an algorithm to verify if a tree is a binary search tree.
Divide two numbers without using / or % and return quotient.
Using only putchar how would you print out the ascii values for each digit in an integer. For example if the integer was 123, then you would want to print the ascii values for 1, 2, and 3.
