Given two unsigned integer values, write a function that returns the first divided by the second. You cannot (of course) use div or mod operators - only addition, subtraction and multiplication. Discuss the strengths/weaknesses/algorithmic complexity of your solution. Is there a better way to do it? If so, what, and what is its complexity?
A list with a set of integers. All elements appear even number of times while one appear odd number of times. Find this number that appear odd number of times
Design a system for counting how many times an item is clicked on. You need to record clicks and be able to report how many clicks for a given item. Be able to report which items are the most popular. Keep in mind scalability, since this is Amazon we're talking about.
What is the time complexity of your solution?
If we write for(i=0;i<10;i++); printf("%d",i); What will be the output?
Given the following list of objects {user, loginTime, logoutTime}. What is the maximum number of concurrent users logged in at the same time? Input: [ {user: A, login: 1, logout: 3}, {user: B, login: 3, logout: 4}, {user: C, login: 1, logout: 2}, {user: D, login: 123123123, logout: 987987987}, {user: E, login: 1, logout: 3} ] Output: 3
