Considering a 2-dimension matrix that can only be traversed by 1 adjacent position at a time and never diagonally. Create an algorithm to traverse that matrix from its upper-left corner to its lower-right corner using the shorter possible path in the most efficient way.
How do you find 2 missing elements in an array of consecutive integers that are not sorted who's size is N-2.
Find if given text does have matching [ { ( opening and closing. So ({[]}) is valid and ({)} is invalid. They should open and close in proper order.
Given an integer array, write a program that returns an array with elements = product of the integers in input array except the one in its position. Ex: Given input: [2, 3, 10, 4, 5], output: [600, 400, 120, 300, 240] What is the complexity of your program? When will your program not work? Below is what I presented (O(n)), but it did not qualify me for the next round.
public class Person { Person father; Person mother; Gender gender; Integer age; List<Person> children; int level = 0; public enum Gender { Male, Female; } } For the above class, you basically have to implement 2 methods. public List<Person> getOldestSisters() public List<Person> getGreatestAncestors()
Given unsorted array, find the 2 max numbers in it.
