1. Find the minimum number of train stations required given a list of departure and arrival times. 2. The online screens had a couple of SAT style questions and some debugging questions.
The input to a function is an array of n elements.Output of that function is also an array where each element is product of all elements in the input array except the one with same index. Input ::::: 1 2 3 4 Output ::::: 2*3*4 1*3*4 1*2*4 1*2*3
Hasp map concepts theory questions coding question : Program to check if binary tree is a BST Complexity of the module written
Given a binary search tree and a number find the closest node to that number.
Give you an array of integers without duplication. Let you write a piece of code to return the pairs that their sum is 100.
Given a linked list, flip every pair of nodes, such that if given a-b-c-d-e, return b-a-d-c-e.
If you get an array of integers, find the only integer that is repeated for an odd number of times.
