As perguntas específicas que você deverá responder dependerão do tipo de cargo de engenharia que você está procurando, por exemplo, se é uma determinada disciplina da engenharia, como software, elétrica ou mecânica.
class A { public A() { foo(); } public void foo() { System.out.println("Class A"); } } class B extends A { public B(){} public void foo() { System.out.println("Class B"); } } class main { public static void main(String[] args) { A a = new B(); } } What does it print? Class A or Class B?
Given two strings representing integer numbers ("123" , "30") return a string representing the sum of the two numbers ("153")
Find number of ones in an integer.
Write a function(int[]) -> int that returns the lowest unassigned integer. For example [] -> 1 (empty set), [1] -> 2, [5, 3, 1] -> 2. Basically just sort the array, iterate, and compare current and previous. If there is a gap then that's your number.
If you have an unsorted array of numbers from 1-100, except 1 of those numbers is missing, how do you determine which number is missing
given a list of tuples of movie watched times, find how many unique minutes of the movie did the viewer watch e.g. [(0,15),(10,25)]. The viewer watched 25 minutes of the movie.
Print a binary tree by vertical level order like 1 2 4 3 5 print : 3 2 1 5 4
given an array of numbers to remove the duplicates
Phone interview question: Given a string pattern of 0s, 1s, and ?s (wildcards), generate all 0-1 strings that match this pattern. e.g. 1?00?101 -> [10000101, 10001101, 11000101, 11001101]. You can generate the strings in any order that suits you.
